Functions
const std::array< float, 2 *kColorTransferSampleCount > &	donner::gpu::shader::programs::ColorTransferSamples ()
	Returns the process-lifetime transfer samples in the shader's table order.
const CompiledShaderView &	donner::gpu::shader::programs::ColorSpaceConvertShader ()
	Returns the WGSL color-space artifact: straight-alpha channels pass through the selected half of the transfer table.
const CompiledShaderView &	donner::gpu::shader::programs::ColorSpaceConvertNativeShader ()
	Returns only the platform-native ColorSpaceConvert projection.

Variables
constexpr uint32_t	donner::gpu::shader::programs::kColorSpaceConvertSrgbToLinear = 0
	Direction value converting sRGB input to linear output.
constexpr uint32_t	donner::gpu::shader::programs::kColorSpaceConvertLinearToSrgb = 1
	Direction value converting linear input to sRGB output.
constexpr uint32_t	donner::gpu::shader::programs::kColorTransferSampleCount = 4096
	Samples per transfer direction; the table holds the forward then the inverse curve.
