98cf38601f render: replace wlr_texture_write_pixels with update_from_buffer 
This lets the renderer handle the wlr_buffer directly, just like it
does in texture_from_buffer. This also allows the renderer to batch
the rectangle updates, and update more than the damage region if
desirable (e.g. too many rects), so can be more efficient.

29291cb47c render/texture: drop wlr_texture_is_opaque 
Whether a texture is opaque or not doesn't depend on the renderer
at all, it just depends on the source buffer. Instead of forcing
all renderers to implement wlr_texture_impl.is_opaque, let's move
this in common code and use the wlr_buffer format to know whether
a texture will be opaque.

35d1bcff6f render/vulkan/pixel_format: do not leak props->... 
`vulkan_format_props_query` calls `query_modifier_support` which
initializes fields of `props` with allocated memory. this memory is
leaked if `query_modifier_support` does not find a supported format
and shmtex is not supported, as in this case `add_fmt_props` ends
up being false and the allocated fields of `props` are never freed.

96b594110d matrix: remove wlr_matrix_projection() 
69477051cc ("matrix: deprecate wlr_matrix_projection") marked it
as deprecated. 1 year later, we can now remove it from our public
API.

d8d30463ac render/vulkan: log physical device driver name 
This can be useful to figure out why a required feature is missing,
e.g. as in [1].

We check VK_EXT_physical_device_drm availability after printing
the driver name.

With some bit magic, we can get something much nicer:

  v_add_u32     v0, s2, v0                              // 000000000000: 68000002

  v_and_b32     v1, 2, v1                               // 000000000008: 26020282
  v_cvt_f32_i32  v1, v1                                 // 00000000000C: 7E020B01
  v_mul_f32     v1, 0.5, v1                             // 000000000010: 0A0202F0
  v_and_b32     v0, 2, v0                               // 000000000014: 26000082
  v_cvt_f32_i32  v0, v0                                 // 000000000018: 7E000B00
  v_mul_f32     v0, 0.5, v0                             // 00000000001C: 0A0000F0
  v_mov_b32     v2, 0                                   // 000000000020: 7E040280
  v_mov_b32     v3, 1.0                                 // 000000000024: 7E0602F2
  exp           pos0, v1, v0, v2, v3 done               // 000000000028: C40008CF 03020001
  exp           param0, off, off, off, off              // 000000000030: C4000200 00000000
  s_endpgm                                              // 000000000038: BF810000

The above output was based on just shoving it in ShaderPlayground -- I was not able to use pipeline feedback as I was unable to get RenderDoc working due to the EXT_physical_device_drm requirement.

I additionally considered using >> 1 instead of * 0.5, but AMD has dedicated modifiers to merge a * 0.5, * 2.0, etc in a single instruction. (Albeit, not taken advantage of in the code above, but might with ACO)

This suppresses the output filename printed to stdout. Errors and
warnings should still be printed to stderr as usual.

a04cfca4da Remove support for DMA-BUF flags 
They are never used in practice, which makes all of our flag
handling effectively dead code. Also, APIs such as KMS don't
provide a good way to deal with the flags. Let's just fail the
DMA-BUF import when clients provide flags.

8e34692250 render/vulkan: add Vulkan renderer 
This new renderer is implemented with the existing wlr_renderer API
(which is known to be sub-optimal for some operations). It's not
used by default, but users can opt-in by setting WLR_RENDERER=vulkan.

The renderer depends on VK_EXT_image_drm_format_modifier and
VK_EXT_physical_device_drm.
