D3D11: Fix dEQP shader's texture function failures #925

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
dEQP is failing a few tests in dEQP-GLES3.functional.shaders.texture_functions.

A few fixes related to shadow samplers when they are used with either:
- textureProj
- vertex shaders
https://chromium-review.googlesource.com/#/c/251530/

Most of the remaining failures are due to some combinations of sampling mode 
which are not directly supported by DirectX. For instance, to get textureGrad 
working with shadow samplers, I think that we have to emulate the comparison 
inside the shader — which is tricky because the comparison function is not 
known until the draw call.
