Add sampler3DShadow support #153

Closed archimedus closed 3 years ago

archimedus commented 3 years ago

Extending depth texture tests in CTS I noticed that we do not have sampler3DShadow, though Vulkan (and it SPIR-V) allows it.

We have support in GLSL for almost all depth texture types (sampler2DShadow, samplerCubeShadow, sampler2DArrayShadow, sampler1DShadow, sampler1DArrayShadow, and samplerCubeArrayShadow). May be it's worthy to extend GLSL with support of sampler3DShadow?

Also appropriate overloads for functions like texture() will be required.

Internal vk-gl-cts issue 2521.

It may be that Vulkan does not intend to allow this. This will be resolved inside Khronos.

Vulkan has clarified that this is not allowed, so there's no need for GLSL support.
