This reverts commit 019814e2c1.
 2022-08-08 23:16:34 -07:00
bjorn a2ee485d41 Fix most windows warnings in graphics code; 
Co-authored-by: mcc <andi.m.mcclure@gmail.com>

bjorn 019814e2c1 Change the way modules are destroyed; 
They are now destroyed explicitly after tearing down the Lua state
instead of relying on finalizers.  It's definitely annoying to make it
coordinated in a centralized way like this instead of being distributed,
but there's not really any reliabel way to ensure that graphics objects
are destroyed before the graphics module/device is destroyed, which is a
problem.

bjorn 16860e8ef5 rm stats; 
These stats don't make sense right now.

bjorn acd87a5e5c lovr.graphics.present; 
It's nice to have an explicit action for presentation.

bjorn 89312c1c4b Add on-disk shader cache; 
Set t.graphics.shadercache to true (the default) and lovr will
read/write a shader cache file from/to disk.
 2022-08-02 22:06:44 -07:00
bjorn 4ee092e81b Make Pass a regular object; 
It uses newPass instead of getPass.  Temporary objects had lifetime
issues that were nearly impossible to solve.  And normal objects are
easier to understand because they behave like all other LÖVR objects.

However, Pass commands are not retained from frame to frame.  Pass
objects must be re-recorded before every submit, and must be reset
before being recorded again.

Pass objects now provide a natural place for render-pass-related info
like clears and texture handles.  They also allow more information to be
precomputed which should reduce overhead a bit.

It is now possible to request a stencil buffer and antialiasing on the
window and headset textures, via conf.lua.

lovr.graphics.setBackground should instead set the clear color on the
window pass.  Though we're still going to try to do spherical harmonics
in some capacity.

There are still major issues with OpenXR that are going to be ironed
out, and the desktop driver hasn't been converted over to the new
headset Pass system yet.  So lovr.headset integration is a bit WIP.

bjorn f89b1811aa Adjust default Buffer field locations; 
I guess it's better to match them up with the default attributes.
In most cases you're going to want to manually specify them with names
or numbers anyway.

bjorn cbe24f482f Adjust font uvs; 
- Padding is automatically computed from spread.
  - Spread increases detail at small sizes.
  - Remove failure cases where padding < spread/2
- UVs are un16x2, making room for color
- Don't center glyphs inside their atlas bounding box
- Cache normalized UVs and update them (for glyphs and vertices) when
  the atlas changes size.
  - Updating the UVs is UGLY and duplicates a lot of code.  It may be
    better to normalize the UVs on the fly, or just re-render the entire
    string if the atlas is updated.

You can't actually write any data to the buffer yet, since we don't have

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 b22dbd8f0c Add luax_checku32 and luax_optu32; 
These functions read an unsigned 32 bit integer from the Lua stack
and error if the value is negative or too big.  Currently converting
Lua numbers to integers will silently wrap or invoke undefined behavior
when they are outside of the acceptable range.

For projects that don't want the overhead of type/bounds checks, the
supercharge build option (LOVR_UNCHECKED) can now be used to skip all
type/bounds checks.

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.
