ES31: Support textureGather[Offset] on shadow samplers This patch implements translating textureGather[Offset] into HLSL when the sampler is a shadow sampler. The related HLSL function should be GatherCmp(). According to the definition of textureGatherOffset(): ([ESSL 3.1] Chapter 8.9.3 Page 138) - gvec4 textureGatherOffset(gsampler2D sampler, vec2 P, ivec2 offset, [,int comp]) - vec4 textureGatherOffset(sampler2DShadow sampler, vec2 P, float refZ, ivec2 offset) We need to add parameter "refZ" before "offset" when the sampler is a shadow sampler.
