window_properties is documented to contain a subset of the X11 properties
of a window (its title, class, instance, role, and transient ID). This
commit adds the missing json object from the get_tree output for
xwayland windows only.
This is a follow-up of #2911.

QT unmaps the view before destroying the popup. We destroyed the popup
in response to the view unmapping, but then we'd attempt to destroy it a
second time which caused a crash.
The patch removes the listener.
I tested it with GTK as well, and can confirm the popup is still being
destroyed.
* When using multiple seats, each seat has its own prev_workspace_name
for the purpose of workspace back_and_forth.
* Removes prev_workspace_name global variable.
* Removes unused next_name_map function in tree/workspace.c.
* Fixes memory leak in seat_destroy (seat was not freed).
The directive controlled whether floating views should raise to the top
when the cursor is moved over it while using focus_follows_mouse. The
default was enabled, which is undesirable. For example, if you have two
floating views where one completely covers the other, the smaller one
would be inaccessible because moving the mouse over the bigger one would
raise it above the smaller one.
There is no known use case for having raise_floating enabled, so this
patch removes the directive and implements the raise_floating disabled
behaviour instead.
The input manager is a singleton object. Passing the sway_input_manager
argument to each of its functions is unnecessary, while removing the
argument makes it obvious to the caller that it's a singleton. This
patch removes the argument and makes the input manager use server.input
instead.
On a similar note:
* sway_input_manager.server is removed in favour of using the server
global.
* seat.input is removed because it can get it from server.input.
Due to a circular dependency, creating seat0 is now done directly in
server_init rather than in input_manager_create. This is because
creating seats must be done after server.input is set.
Lastly, it now stores the default seat name using a constant and removes
a second reference to seat0 (in input_manager_get_default_seat).
Fixes a regression introduced in
24a90e5d86.
consider_warp_to_focus has been renamed to seat_consider_warp_to_focus,
moved to seat.c and made public. It is now called when switching
workspaces via `workspace <ws>`.
Because cursor warping was the default behaviour in seat_set_focus,
there may be cases where we may have been warping the cursor
unintentionally. This patch removes cursor warping from seat_set_focus
and only does it in the focus command. This is managed by a static
function in focus.c.
To know whether to warp or not, we need to know which node had focus
previously. To keep track of this easily, seat->prev_focus has been
introduced and is set to the previous in seat_set_focus.
The new functions allow a cursor to be warped without changing the focus.
This is a preparation commit to handle cursor warping not only in
seat_set_focus_warp.
For mouse_warping cursor to correctly work on newly spawned containers,
the workspace needs to be arranged before the cursor is warped.
The shell functions each implement their own fullscreen and arrange checks,
move them into the view_map function and pass their states via boolean arguments.
Fixes#2819
Previously we would compare the last focus's workspace with the new
focus's workspace to determine if we need to emit an IPC
workspace::focus event. This doesn't work when moving the focused
container to a new workspace.
This adds a workspace property to the seat which stores the last emitted
workspace::focus workspace. Using this method, after moving the
container, refocusing it will trigger exactly one workspace::focus
event: from the old workspace to the new workspace.
This introduces seat_set_raw_focus: a function that manipulates the
focus stack without doing any other behaviour whatsoever. There are a
few places where this is useful, such as where we set focus_inactive
followed by another call to set the real focus again. With this change,
the notify argument to seat_set_focus_warp is also removed as these
cases now use the raw function instead.
A bonus of this is we are no longer emitting window::focus IPC events
when setting focus_inactive, nor are we sending focus/unfocus events to
the surface.
This also fixes the following:
* When running `move workspace to output <name>` and moving the last
workspace from the source output, the workspace::focus IPC event is no
longer emitted for the newly created workspace.
* When splitting the currently focused container, unfocus/focus events
will not be sent to the surface when giving focus_inactive to the newly
created parent, and window::focus events will not be emitted.
* The loop functions are now prefixed with `loop_`.
* It is now easy to add timers to the loop.
* Timers are implemented using pollfd and timerfd, rather than manually
checking them when any other event happens to arrive.
Since wayland does not currently allow swaybar to create global
keybinds, this is handled within sway and sent to the bar using a custom
event, so as not to pollute existing events, called bar_state_update.
As well as adding the hidden_state property to the bar config struct,
this commit handles barconfig_update events when the mode or
hidden_state changes, and uses a new function determine_bar_visibility
to hide or show the bar as required, using, respectively,
destroy_layer_surface, which is also newly added, and add_layer_surface,
which has been changed to allow dynamically adding the surface.
This distinguishes the binding mode from the distinct config mode, as
well as removing mode_pango_markup from the config struct where it
should not be present.
While allowing negative values for the outer gaps it is still prevented that negative values move windows out of the container. This replaces the non-i3 option for edge_gaps.
Returning a boolean from container_resize_tiled and resize_tiled doesn't
work in all cases. This patch changes it back to void and does a
before/after check to see if the container was resized.
This introduces a new view_impl function: is_transient_for. Similar to
container_has_ancestor but works using the surface parents rather than
the tree.
This patch modifies view_is_visible, container_at and so on to allow
transient views to function normally when they're in front of a
fullscreen view.
This patch makes it so when you run reload, the actual reloading is
deferred to the next time the event loop becomes idle. This avoids
several use-after-frees and removes the workarounds we have to avoid
them.
When you run reload, we validate the config before creating the idle
event. This is so the reload command will still return an error if there
are validation errors. To allow this, load_main_config has been adjusted
so it doesn't apply the config if validating is true rather than
applying it unconditionally.
This also fixes a memory leak in the reload command where if the config
failed to load, the bar_ids list would not be freed.
The previous behaviour was to damage the entire view, which would
recurse into each popup. This patch makes it damage only the popup's
surface, and respect the surface damage given by the client.
This adds listeners to the popup's map and unmap events rather than
doing the damage in the create and destroy functions. To get the popup's
position relative to the view, a new child_impl function get_root_coords
has been introduced, which traverses up the parents.
Re-focus on the container on which the cursor hovers over. A
special case is, if there are menus or other subsurfaces open
in the focused container. It will prefer the focused container
as long as there are subsurfaces.
This commit starts caching the previous node as well as the
previous x/y cursor position. Re-calculating the previous
focused node by looking at the current state of the cursor
position does not work, if the environment changes.
* New configuration option: raise_floating
(From the discussion on https://github.com/i3/i3/issues/2990)
* By default, it still raises the window on focus, otherwise it
will raise the window on click.
Fixes `hide_edge_borders smart` when gaps are in use.
Implements `hide_edge_borders smart_no_gaps` and `smart_borders
on|no_gaps|off`.
Since `smart_borders on` is equivalent to `hide_edge_borders smart`
and `smart_borders no_gaps` is equivalent to `hide_edge_borders
smart_no_gaps`, I opted to just save the last value set for
`hide_edge_borders` and restore that on `smart_borders off`. This
simplifies the conditions for setting the border.
This changes our gaps implementation to behave like i3-gaps.
Our previous implementation allowed you to set gaps on a per container
basis. This isn't supported by i3-gaps and doesn't seem to have a
practical use case. The gaps_outer and gaps_inner properties on
containers are now removed as they just read the gaps_inner from the
workspace.
`gaps inner|outer <px>` no longer changes the gaps for all workspaces.
It only sets defaults for new workspaces.
`gaps inner|outer current|workspace|all set|plus|minus <px>` is now
runtime only, and the workspace option is now removed. `current` now
sets gaps for the current workspace as opposed to the current container.
`workspace <ws> gaps inner|outer <px>` is now implemented. This sets
defaults for a workspace.
This also fixes a bug where changing the layout of a split container
from linear to tabbed would cause gaps to not be applied to it until you
switch to another workspace and back.
When we eventually implement `workspace <ws> gaps inner|outer <px>`,
we'll need to store the gaps settings for workspaces before they're
created. Rather than create a workspace_gaps struct, the approach I'm
taking is to rename workspace_outputs to workspace_configs and then add
gaps settings to that.
I've added a lookup function workspace_find_config. Note that we have a
similar thing for outputs (output_config struct and output_find_config).
Lastly, when freeing config it would create a memory leak by freeing the
list items but not the workspace or output names inside them. This has
been rectified using a free_workspace_config function.
This involves setuid'ing swaylock, which then forks and drops perms on
the parent process. The child process remains root and listens on a pipe
for requests to validate passwords against /etc/shadow.
This does the following:
* Removes the xdg-decoration surface_commit listener. I was under the
impression the client could ignore the server's preference and set
whatever decoration they like using this protocol, but I don't think
that's right.
* Adds a listener for the xdg-decoration request_mode signal. The
protocol states that the server should respond to this with its
preference. We'll always respond with SSD here.
* Makes it so tiled views which use CSD will still have sway decorations
rendered. To do this, using_csd had to be added back to the view struct,
and the border is changed when floating or unfloating a view.
This replaces view.using_csd with a new border mode: B_CSD. This also
removes sway_xdg_shell{_v6}_view.deco_mode and
view->has_client_side_decorations as we can now get these from the
border.
You can use `border toggle` to cycle through the modes including CSD, or
use `border csd` to set it directly. The client must support the
xdg-decoration protocol, and the only client I know of that does is the
example in wlroots.
If the client switches from SSD to CSD without us expecting it (via the
server-decoration protocol), we stash the previous border type into
view.saved_border so we can restore it if the client returns to SSD. I
haven't found a way to test this though.
This adds a `con` argument to `execute_command` which allows you to
specify the container to execute the command on. In most cases it leaves
it as `NULL` which makes it use the focused node. We only set it when
executing `for_window` criteria such as when a view maps. This means we
don't send unnecessary IPC focus events, and fixes a crash when the
criteria command is `move scratchpad` (because we can't give focus to a
hidden scratchpad container).
Each of the shell map handlers now check to see if the view has a
workspace. It won't have a workspace if criteria has moved it to the
scratchpad.
Fixes#2674.
The cause of the issue was in get_pango_layout. When we call
pango_parse_markup, `text` is the escaped string, and the unescaped
string is then computed and written to `buf`. We were then passing the
unescaped string to pango_layout_set_markup, but this function needs the
escaped string. `buf` is not needed and has been removed.
The other part of this PR refactors escape_markup_text to remove the
dest_length argument and removes the -1 return value on error. It now
assumes that you've allocated dest to the correct length.
This now correctly handles an incoming json infinite array by shifting
most of the heavy listing to the json-c parser, as well as sending
multiple statuses at once. It also removes the struct
i3bar_protocol_state and moves its members into the status_line struct,
allowing the same buffer to be used for both protocols.
This now uses getline to correctly handle multiple or long statuses. It
also removes the struct text_protocol_state and moves its members into
the status_line struct.
This prevents blocks from being destroyed before their hotspots are destroyed,
in case it is used for a pending click event that fires between the bar
receiving a new status, which destroys the block, and the bar rendering the new
status, which destroys the hotspot; this problem can be easily produced by
scrolling on a block that immediately causes a new status to be sent, with
multiple outputs
* Make container_add_sibling's `after` argument a boolean.
* Use a constant for drop layout border
* Make thickness an int
* Add button state check
* Move comments in seat_end_move_tiling
This does the following:
* Adds a baseline argument to get_text_size (the baseline is the
distance from the top of the texture to the baseline).
* Stores the baseline in the container when calculating the title
height.
* Takes the baseline into account when calculating the config's max font
height.
* When rendering, pads the textures according to the baseline so they
line up.
These are the same as seat_set_focus, but accept a specific type rather
than using nodes. Doing this adds more typesafety and lets us avoid
using &con->node which looks a little ugly.
This fixes a crash that pretty much nobody would ever come across. If
you have a bindsym for "focus" with no arguments and run it from an
empty workspace, sway would crash because it assumes `container` is not
NULL.
This commit changes the meaning of sway_container so that it only refers
to layout containers and view containers. Workspaces, outputs and the
root are no longer known as containers. Instead, root, outputs,
workspaces and containers are all a type of node, and containers come in
two types: layout containers and view containers.
In addition to the above, this implements type safe variables. This
means we use specific types such as sway_output and sway_workspace
instead of generic containers or nodes. However, it's worth noting that
in a few places places (eg. seat focus and transactions) referring to
them in a generic way is unavoidable which is why we still use nodes in
some places.
If you want a TL;DR, look at node.h, as well as the struct definitions
for root, output, workspace and container. Note that sway_output now
contains a workspaces list, and workspaces now contain a tiling and
floating list, and containers now contain a pointer back to the
workspace.
There are now functions for seat_get_focused_workspace and
seat_get_focused_container. The latter will return NULL if a workspace
itself is focused. Most other seat functions like seat_get_focus and
seat_set_focus now accept and return nodes.
In the config->handler_context struct, current_container has been
replaced with three pointers: node, container and workspace. node is the
same as what current_container was, while workspace is the workspace
that the node resides on and container is the actual container, which
may be NULL if a workspace itself is focused.
The global root_container variable has been replaced with one simply
called root, which is a pointer to the sway_root instance.
The way outputs are created, enabled, disabled and destroyed has
changed. Previously we'd wrap the sway_output in a container when it is
enabled, but as we don't have containers any more it needs a different
approach. The output_create and output_destroy functions previously
created/destroyed the container, but now they create/destroy the
sway_output. There is a new function output_disable to disable an output
without destroying it.
Containers have a new view property. If this is populated then the
container is a view container, otherwise it's a layout container. Like
before, this property is immutable for the life of the container.
Containers have both a `sway_container *parent` and
`sway_workspace *workspace`. As we use specific types now, parent cannot
point to a workspace so it'll be NULL for containers which are direct
children of the workspace. The workspace property is set for all
containers, except those which are hidden in the scratchpad as they have
no workspace.
In some cases we need to refer to workspaces in a container-like way.
For example, workspaces have layout and children, but when using
specific types this makes it difficult. Likewise, it's difficult for a
container to get its parent's layout when the parent could be another
container or a workspace. To make it easier, some helper functions have
been created: container_parent_layout and container_get_siblings.
container_remove_child has been renamed to container_detach and
container_replace_child has been renamed to container_replace.
`container_handle_fullscreen_reparent(con, old_parent)` has had the
old_parent removed. We now unfullscreen the workspace when detaching the
container, so this function is simplified and only needs one argument
now.
container_notify_subtree_changed has been renamed to
container_update_representation. This is more descriptive of its
purpose. I also wanted to be able to call it with whatever container was
changed rather than the container's parent, which makes bubbling up to
the workspace easier.
There are now state structs per node thing. ie. sway_output_state,
sway_workspace_state and sway_container_state.
The focus, move and layout commands have been completely refactored to
work with the specific types. I considered making these a separate PR,
but I'd be backporting my changes only to replace them again, and it's
easier just to test everything at once.
Fixes#2568
The binding that gets stored in the keyboard's `repeat_binding` would
get freed on reload, leaving a dangling pointer.
Rather than attempt to unset the keyboard's `repeat_binding` along with
the other bindings, I opted to just not set it for the reload command
because there's no point in reloading repeatedly by holding the binding.
This disables repeat bindings for the reload command.
As we now need to detect whether it's a reload command in two places,
I've added a binding flag to track whether it's a reload or not.
This commit changes the arrange code in a way that will support type
safe arguments.
The arrange_output et al functions are now public, however I opted not
to use them directly yet. I've kept the generic arrange_windows there
for convenience until type safety is fully implemented. This means this
patch has much less risk of breaking things as it would otherwise.
To be type safe, arrange_children_of cannot exist in its previous form
because the thing passed to it could be either a workspace or a
container. So it's now renamed to arrange_children and accepts a list_t,
as well as the parent layout and parent's box.
There was some code which checked the grandparent's layout to see if it
was tabbed or stacked and adjusted the Y offset of the grandchild
accordingly. Accessing the grandparent layout isn't easy when using type
safe arguments, and it seemed odd to even need to do this. I determined
that this was needed because a child of a tabbed container would have a
swayc Y matching the top of the tab bar. I've changed this so a child of
a tabbed container will have a swayc Y matching the bottom of the tab
bar, which means we don't need to access the grandparent layout. Some
tweaks to the rendering and autoconfigure code have been made to
implement this, and the container_at code appears to work without
needing any changes.
arrange_children_of (now arrange_children) would check if the parent had
gaps and would copy them to the child, effectively making the
workspace's gaps recurse into all children. We can't do this any more
without passing has_gaps, gaps_inner and gaps_outer as arguments to
arrange_children, so I've changed the add_gaps function to retrieve it
from the workspace directly.
apply_tabbed_or_stacked_layout has been split into two functions, as it
had different logic depending on the layout.
Lastly, arrange.h had an unnecessary include of transaction.h. I've
removed it, which means I've had to add it to several other files.
When we have type safety we'll need to have functions for
workspace_add_tiling and so on. This means the existing container
functions will be just for containers, so they are being moved to
container.c. At this point layout.c doesn't contain much else, so I've
relocated everything and removed the file.
* container_swap and its static functions have been moved to the swap
command and made static.
* container_recursive_resize has been moved to the resize command and
made static.
* The following have been moved to container.c:
* container_handle_fullscreen_reparent
* container_insert_child
* container_add_sibling
* container_add_child
* container_remove_child
* container_replace_child
* container_split
* enum movement_direction and sway_dir_to_wlr have been moved to util.c.
Side note: Several commands included layout.h which then included
root.h. With layout.h gone, root.h has to be included by those commands.
This list includes disabled outputs.
When sway_container is demoted, we'll need to store the root's children
(ie. enabled outputs) in the sway_root. It makes sense to put these in a
list called `outputs`, so I'm renaming the existing list in advance.
* container_move is only called from the move command
* container_move_to was called from both the move command and the sticky
command, but the sticky command can easily not call it
* container_get_in_direction is only called from the focus command
Moving these functions to their respective commands gives better
separation of code and removes bloat from layout.c. These functions will
need to be refactored to take advantage of type safety, so separating
them will make this easier to refactor.
The following static functions have also been moved:
* is_parellel
* invert_movement
* move_offs
* container_limit
* workspace_rejigger
* move_out_of_tabs_stacks
* get_swayc_in_output_direction
They were all used by the move functions, except for the last one which
is used by focus.
Other changes:
* index_child has been renamed to container_sibling_index, moved to
container.c and made public
* sway_output_from_wlr has been renamed to output_from_wlr_output, moved
to output.c and made public
* container_handle_fullscreen_reparent has been made public
* sway_dir_to_wlr has been made public
No changes have been made to any of the moved functions, other than
updating calls to functions that have been renamed.
This changes the destroy functions to the following:
* output_begin_destroy
* output_destroy
* workspace_begin_destroy
* workspace_destroy
* container_begin_destroy
* container_destroy
* view_begin_destroy
* view_destroy
The terminology was `destroy` and `free`, and it has been changed to
`begin_destroy` and `destroy` respectively.
When the last output is disconnected, its workspaces will now be stashed
in the root. Upon connection of a new output they will be restored.
There is a new function `workspace_consider_destroy` which decides
whether the given workspace should be destroyed or not (ie. empty and
not visible).
Calling container_begin_destroy will no longer automatically reap the
parents. In some places we want to reap the parents and in some we
don't, so this is left to the caller.
container_reap_empty_recursive and container_reap_empty have been
combined into one function and it will recurse up the tree.
Previously we used a reparent event to detect when a view changes
parent, then sent an output enter/leave to the surfaces if needed. This
worked for tiling views but not floating views, as floating views can
intersect another output without changing parent.
The solution implemented for floating views also applies cleanly to
tiling views, so the previous method has been completely replaced and
the reparent event has been removed.
This introduces a new function container_discover_outputs. This function
compares the container's `current` position to the outputs, sends enter
and leave events as needed, and keeps track of which outputs it's
intersecting in a new `container->outputs` list. If it has entered a new
output with a different scale then the title and marks textures will
also be recreated at the new scale.
The function is called when a transaction applies. This is convenient as
it means we don't have to call it from various places.
There is imperfect rendering when a floating view overlaps two outputs
with different scales. It renders correctly for the most recently
entered output, but there is only one title texture so it renders
incorrectly on the old output.
Fixes#2482
Workspaces previously had a magical `workspace->floating` container,
which had a layout of L_FLOATING and whose children were actual floating
views. This allowed some conveniences, but was a hacky solution because
the container has to be exempt from focus, coordinate transactions with
the workspace, and omit emitting IPC events (which we didn't do).
This commit changes it to be a list directly in the sway_workspace. The
L_FLOATING layout is no longer used so this has been removed as well.
* Fixes incorrect check in the swap command (it checked if the
containers had the L_FLOATING layout, but this layout applied to the
magical container).
* Introduces workspace_add_floating
This makes all debug options stored in a single struct rather than in
various places, changes/fixes the behaviour of existing options, and
introduces some new options.
* Fixes damage issues with `-Drender-tree` texture (by removing scissor)
* Offsets the render tree overlay's `y` position for those who have
swaybar at the top
* Replaces `-Ddamage=rerender` with `-Dnodamage`
* Replaces `-Ddamage=highlight` with `-Dhighlight-damage`
* Replaces `-Dtxn-debug` with `-Dtxn-wait`
* Introduces `-Dnoatomic`
* Removes the `create_time` and `ms_arranging` figures from transactions
and the log message. Transactions are created after arranging and the
create time is of no significance.
* Fixes `-Dtxn-debug` (now `-Dtxn-wait`) not working.
This introduces the following `for_each` functions:
* root_for_each_workspace
* root_for_each_container
* output_for_each_workspace
* output_for_each_container
* workspace_for_each_container
And introduces the following `find` functions:
* root_find_output
* root_find_workspace
* root_find_container
* output_find_workspace
* output_find_container
* workspace_find_container
* container_find_child
And removes the following functions:
* container_descendants
* container_for_each_descendant
* container_find
This change is preparing the way for demoting sway_container. Eventually
these functions will accept and return sway_outputs, sway_workspaces and
sway_containers (meaning a C_CONTAINER or C_VIEW).
This change also makes it easy to handle abnormalities like the
workspace floating list, root's scratchpad list and (once implemented)
root's saved workspaces list for when there's no connected outputs.
This commit renames container_sort_workspaces to output_sort_workspaces
and moves it to output.c.
This also renames container_wrap_children to workspace_wrap_children and
moves it to workspace.c. This function is only called with workspaces.
This fixes a race condition flicker when unfloating a view which uses
client side decorations.
When the view is floated it has using_csd = true, so the decorations are
not drawn. When unfloating it it changes to false, but this change
wasn't part of transactions so it could potentially render the
decorations around the view while it's waiting for the transaction to
apply.
Fixes#2467.
This commit introduces seat_get_focus_inactive_floating to supplement
seat_get_focus_inactive_tiling, and uses it during `focus mode_toggle`
which fixes a focus bug.
This also refactors the seat_get_focus_inactive functions so that they
do their selection logic themselves rather than offloading it to
seat_get_focus_by_type which was getting bloated. seat_get_focus_by_type
is now removed.
Lastly, this commit changes seat_get_focus to just return the first
container in the focus stack rather than looping and calling
seat_get_focus_by_type.
The original purpose of this commit is to replace some for loops with
list_find. But while doing this I found the workspace_prev_next_impl
functions to be difficult to read and also contained a bug, so I
refactored them and fixed the bug.
To reproduce the bug:
* Have two outputs, where the left output has workspaces 1, 2, 3 and the
right output has workspaces 4, 5, 6. Make workspace 2 focused_inactive
and workspace 4 focused.
* Run `workspace prev`.
* Previously it would visit the left output, then apply `workspace prev`
to workspace 2, which focuses workspace 1.
* Now it will focus the rightmost workspace on the left output
(workspace 3).
The refactoring I made to the workspace functions are:
* Added the static keyword.
* They now accept an int dir rather than bool, to avoid an unnecessary
conversion.
* Rather than preparing start and end variables for the purpose of
iterating, just iterate everything.
* Replace for loops with list_find.
* Don't call workspace_output_prev_next_impl (this fixes the bug).
Commit 4b8e3a885b makes it so only one
transaction is committed (ie. configures sent) at a time. This commit
removes the now-unnecessary code which was used to support concurrent
committed transactions.
* Instead of containers storing a list of instructions which they've
been sent, it now stores a single instruction.
* Containers now have an ntxnrefs property. Previously we knew how many
references there were by the length of the instruction list.
* Instructions no longer need a ready property. It was used to avoid
marking an instruction ready twice when they were in a list, but this is
now avoided because there is only one instruction and we nullify the
container->instruction pointer when it's ready.
* When a transaction applies, we no longer need to consider releasing
and resaving the surface, as we know there are no other committed
transactions.
* transaction_notify_view_ready has been renamed to
view_notify_view_ready_by_serial to make it consistent with
transaction_notify_view_ready_by_size.
* Out-of-memory checks have been added when creating transactions and
instructions.
* The OP_RESIZE seat operation has been renamed to OP_RESIZE_FLOATING,
and OP_RESIZE_TILING has been introduced.
* Similar to the above, seat_begin_resize and handle_resize_motion have
been renamed and tiling variants introduced.
* resize.c's resize_tiled has to be used, so container_resize_tiled has
been introduced in resize.c to allow external code to call it.
This allows for a color to be set when the wallpaper does not fill the
entire output. If specified, the fallback color is also used when the
image path is inaccessible.
Rationale: Sticky containers are always assigned to the visible
workspace.
The basic idea here is to check the destination's output (move.c:190).
But if the command was `move container to workspace x` then a workspace
might have been created for it. We could destroy the workspace in this
case, but that results in unnecessary IPC events.
To avoid this, the logic for `move container to workspace x` has been
adjusted. It now delays creating the workspace until the end, and uses
`workspace_get_initial_output` to determine and check the output before
creating it.
* Removes container_floating_move_to_container, instead opting to put
that logic in container_move_to
* In the seat code, focusing a floating view now updates the pending
state only and lets the next transaction carry it over to the current
state. This is required, otherwise it would crash.
* When unfullscreening a floating container, an output check is now done
to see if it should center it.
