604fcdb1db render/vulkan: clip negative values before applying transfer function 
Not all eotf or eotf inverse are well defined for values outside the
intended domain, so just ignore it and clamp it away.

An alternative solution would be to use sign preserving pow here (i.e.
sign(x) * pow(abs(x), p)), however I'm not sure that makes sense or is
defined anywhere. Negative values here are likely a result of colors
being outside the gamut range, so clipping them to 0 is more correct
than mirroring from 0.

5adf325333 render/vulkan: undo alpha premult before sRGB encoding/decoding 
sRGB encoding/decoding needs to happen with straight alpha, not
pre-multiplied alpha.

3ed69b4946 render/vulkan: add support for RGB565 texture format 
Since this does not have a matching _SRGB-type vulkan format, add a
new shader variant/pipeline to perform the sRGB->linear texture
conversion.

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.
