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.
The important bit here is whether this is using a single or two
sub-passes. The flag isn't used for anything else.
Preparation for an upcoming one-subpass codepath.
A combined image sampler may need several descriptors in a descriptor
set. We are not currently checking how many descriptors are required,
nor is it presumably guaranteed that such multi-descriptor allocation
will not fail due to fragmentation.
If the pool free counter is not zero, try to allocate but continue with
the next pool and fall back to creating a new pool if the allocation
failed.

We pass an alpha multiplier plus a luminance multiplier now.
Fixes the following validation layer error:
vkCmdPushConstants(): is called with
stageFlags (VK_SHADER_STAGE_FRAGMENT_BIT), offset (80), size (72)
but the VkPipelineLayout 0x510000000051 doesn't have a VkPushConstantRange with VK_SHADER_STAGE_FRAGMENT_BIT.
The Vulkan spec states: For each byte in the range specified by offset and size and for each shader stage in stageFlags, there must be a push constant range in layout that includes that byte and that stage (https://docs.vulkan.org/spec/latest/chapters/descriptorsets.html#VUID-vkCmdPushConstants-offset-01795) (VUID-vkCmdPushConstants-offset-01795)

Commit b4ce0d8b39 ("render/egl: accept negative DRM FD to select
software rendering") added an EXT_device_drm check to figure out
whether the user selected a device with a DRM FD or without one.
However, for KMS-only devices, Mesa will never advertise the
selected KMS node:
3f1d40d230/src/egl/main/egldevice.c (L109)
Instead, pass down a parameter to indicate whether a DRM FD was
passed in.

Converting the LCMS2 transform to a 3D LUT early causes issues:
- It's a lossy process, the consumer will not be able to pick a
3D LUT size on their own.
- It requires unnecessary conversions and allocations: an intermediate
3D LUT is allocated, but the renderer already allocates one.
- It makes it harder to support arbitrary color transforms in the
renderer, because each type needs to be handled differently.
Instead, expose a function to evaluate a color transform, and use
that to build the 3D LUT in the renderer.
