bjorn 513a1876c9 Simplify vertex buffers; 
The default buffer is always bound to slot 0 once at the beginning of
command buffers, reducing the amount of rebinding.

bjorn 355b2bf85b Switch to glslang fork; 
The reason is that the glslang C API doesn't support the extra
overloads that let you provide multiple strings or the lengths for
strings.  In our case our shader blobs are not null terminated, so
sending them to glslang would overrun the buffer.  I forked glslang
and modified the C API to support a length parameter.

- Headset rendering is guaranteed synchronous now, no need to ref L
- Add an "android flavor" build setting to differentiate between oculus

- Update the pico manifest to reflect their OpenXR sample

bjorn c9fe026a66 Fix undefined behavior in arr_free; 
Currently there is a single allocator function used in arr_t.  Its
behavior depends on the values for the pointer and size arguments:

- If pointer is NULL, it should allocate new memory.
- If pointer is non-NULL and size is positive, it should resize memory.
- If size is zero, it should free memory.

All instances of arr_t use realloc for this right now.  The problem
is that realloc's behavior is undefined when the size argument is zero.
On Windows and Linux, realloc will free the pointer, but on macOS this
isn't the case.  This means that arr_t leaks memory on macOS.

It's best to not rely on undefined behavior like this, so let's instead
use a helper function that behaves the way we want.

bjorn 8462beef00 Fix/improve alpha cutoff; 
The current flag did not work because float shader flags are not
supported.  It was also not very useful because it was per-shader
and did not use the alpha cutoff property of glTF materials.

Instead, let's turn the shader flag into an enable/disable boolean,
and add a scalar material property named "alphacutoff" that gets
read by the glTF importer.

When the alphaCutoff flag is enabled, the material property will be
compared against the pixel's alpha value to decide whether it should
get discarded.

bjorn 255ecbb4d8 Fix stencil color mask; 
- When calling lovr.graphics.stencil, the color mask is initially
  disabled, and gets restored to its initial state afterwards.
- However, when it's restored, it uses lovrGraphicsSetColorMask, which
  just sets shadow state that doesn't make it all the way to GL until
  another draw is done.
- The consequence of this is that if you call .stencil and then don't do
  a draw, any clears that happen will use the old (disabled) color mask,
  preventing the color buffer from being cleared.
- The solution here is to lower the color mask change down into opengl.c
  where it can directly hit OpenGL.

bjorn 25bb12d07c Native textures don't destroy their handles; 
If a Texture is created from a handle, that means someone else created
it, so we expect them to destroy it.  We were always destroying handles,
and I guess this was usually okay because glDeleteTextures is idempotent.

However, we're seeing a crash in the Oculus driver when OVR is torn
down.  Presumably it is trying to access its swapchain textures after we
destroyed them.  Not sure why this wasn't an observable issue before,
maybe it's a new regression.  Still, it makes sense to only delete the
GL texture handle if we were the one that created it.

We don't need to check this for the renderbuffer since we always own those.

- Compute feature requires compute shaders, image load/store, and SSBOs.
- GLSL 330 is always used, instead of changing depending on compute shader extension.
- Explicitly enable compute shaders, image load/store, and SSBO extensions when needed.

This allows implementations that don't support GLSL 430 to run compute shaders,
and keeps the min supported GL version more consistently at GL3.3.

bjornbytes 5c381ead34 Force set vsync in lovrGraphicsCreateWindow; 
Headset drivers are allowed to override the vsync setting if vsync
messes up their frame timing.  The vsync property is effectively a
global piece of state in core/os and doesn't change across restarts
because the window is persistent.  This can mean that if you switch
from a headset driver that wants vsync off (anything except desktop)
to a headset driver that doesn't care what the vsync is (desktop),
you could end up with a vsync setting that doesn't match t.window.vsync.
I think this is a symptom of poor design somewhere and the best solution
to this probem is "to just not have it".  Similar issues exist for, e.g.
the window size (but that one is less weird because at least you were
the one who changed it).  For now we are just going to ensure that
lovr.graphics.createWindow always modifies the vsync property.
Untested, may need to adjust this fix later.

bjorn 38875cb399 Fix buffer flushing; 
lovrGraphicsMapBuffer had the potential to cause a flush.  Flushing
unmaps buffers.  This meant that during any of the calls to map while
creating a Batch, it was possible to cause a flush and unmap other
buffers that expected to be mapped.  This caused writes to unmapped
pointers and subsequent skipping of calls to glFlushMappedBufferRange.

The fix is to figure out if we need to flush upfront and get it out
of the way before mapping any buffers.

bjorn 61abb6f02b More strict compute shader test; 
Some hardware supports ARB_compute_shader but not 4.3, causing
shader compilation failures because currently we switch to GLSL 430
if compute shaders are detected.

Instead, just detect GL 4.3 instead of looking for the compute shader
extension.  This means that compute shaders will sometimes be
unavailable even when they're supported.

It would be possible to improve this by modifying the way shaders
are compiled.  Maybe the highest supported GLSL version should be used,
but this makes shader authoring somewhat more difficult.

bjorn 80f9514295 Shader:sendImage only checks srgb flag for RGBA textures; 
It doesn't need to check it for RGB and compressed textures because
those are already rejected.

It may also be a good idea to zero-out the srgb flag for formats that
it doesn't apply to.

bjorn b45baacb66 Handle active attributes that don't have a location; 
There are some attributes that don't have a location (gl_InstanceID
is being reported for some reason).  Their location is -1 and this
causes a left shift of a negative value which is undefined.

ModelData is still allowed to load skins with more joints, since
the limitation is in the graphics side of things (Model).

Eventually we will use a buffer for joints to alleviate this.

GL_DEPTH_TEST controls both whether depth testing and depth writes are
enabled. So if depth testing is disabled and depth writes are enabled,
GL_DEPTH_TEST has to be enabled and the compare mode should be GL_ALWAYS.

bjorn 443376efde ModelData: Use union for transform fields; 
Nodes can have either a transform matrix, or decomposed transform
properties, but never both.  Using a union means we can store both
of those variants in the same piece of memory, using the existing
matrix boolean to figure out which one to use.

This reduces the size of the struct by 48 bytes (152 -> 104), which
ends up speeding up some model operations, I'm guessing due to the
CPU cache.

Cassie Jones 3e09120173 Compile shaders using source lengths 
The previous implementation relied on glShaderSource inferring source
lengths when the lengths weren't specified. This relies on the sources
being properly null-terminated, however, which isn't the case due to
file loading changes which now use pointer + length. This could cause
intermittent crashes.

Changing this on the shader side meant adding some extra arguments for
passing around shader source lengths. For most of the other cases, where
we're using string literals as the sources, we can just specify -1 as
the length, since OpenGL will calculate the string length for you any
time the length is negative.

bjorn 541400e0fe oculus_mobile: Create framebuffers from bridged swapchain textures; 
This is a change that shifts the responsibility regarding the creation
of OpenGL framebuffers from vrapi-provided swapchain texture handles.
Previously, the LovrApp component of lovr-oculus-mobile was creating
framebuffers and passing native framebuffer IDs to lovr.  With this
change, lovr-oculus-mobile passes vrapi's swapchain textures to lovr
unmodified.  This allows lovr to create canvases using its conventional
method and also means that the properties of the canvases are no longer
hardcoded, so things like resolution and multisampling can be
customized.

There were also some issues with multiview canvases in LÖVR due to some
misconceptions about how multisampled multiview rendering works.  These
issues have also been fixed in this commit.
