The Vulkan spec states:
> For the purposes of range expansion and Y′CBCR model conversion,
> the R and B components contain color difference (chroma) values
> and the G component contains luma.
The equations below that sentence also help understand the mapping.
We don't actually need the REPEAT mode, and this makes things more
consistent with the YCbCr sampler (which requires CLAMP_TO_EDGE for
spec compliance).
Also drop borderColor which is unused for this mode.
Fixes the following validation error:
[ VUID-VkImageViewCreateInfo-pNext-01970 ] Object 0: handle = 0x62e00003c400, type = VK_OBJECT_TYPE_DEVICE; | MessageID = 0xf378e14b | vkCreateImageView(): If there is a VkSamplerYcbcrConversion, the imageView must be created with the identity swizzle.
Some formats like sub-sampled YCbCr use a block of bytes to
store the color values for more than one pixel. Update our format
table to be able to handle such formats.
Address Sanitizer reported two memory leaks because of
fmt not being freed in wlr_drm_format_set_copy.
This commit fixes the memory leak by removing the
allocation to the heap. The struct is allocated to the
stack anyway.
This is implemented by a two-subpass rendering scheme; the first
subpass draws (and blends) onto a linear R16G16B16A16_SFLOAT buffer,
while the second subpass performs linear->srgb conversion, writing
onto the actual output buffer.
This fixes the following validation errors when shutting down Sway:

Remove debug logs when a texture is created, since this happens
pretty often. Use drmGetFormatName() and drmGetFormatModifierName()
to log DRM formats and modifiers.
This ensures that the pool sizes grow exponentially, making the number
of pools needed logarithmic in the number of descriptors, instead of
linear. Since the first pool's size is 256, this change only has an
effect when the compositor creates a large number of textures.
Goals:
- Extensibility: we need to be able to add new params to the calls
to render a texture/rect. For instance we'll need to add fences to
the render texture operation for explicit sync purposes.
- No implicit state: no more bind_buffer, begin, end.
- No matrices: these hurt Pixman and we don't need them.
- Clip regions for optimized damage repainting.

Setting the GLESv2 parameter GL_PACK_ALIGNMENT to 1 ensures that the
stride of the glReadPixels output matches the value computed in
`pack_stride`. Since the default value of GL_PACK_ALIGNMENT is 4, this
does not make a difference under normal use; but without this patch
the stride can be incorrect; for example, with RGB565 buffers and
screenshots of regions with odd width.
