NAME
    texCUBEproj - performs a texture lookup with projection in a given
    sampler.

SYNOPSIS
      float4 texCUBEproj(samplerCUBE samp, float4 s)

      int4 texCUBEproj(isamplerCUBE samp, float4 s)

      unsigned int4 texCUBEproj(usamplerCUBE samp, float4 s)

PARAMETERS
    samp    Sampler to lookup.

    s       Coordinates to perform the lookup. The value used in the
            projection should be passed as the last component of the
            coordinate vector.

    texelOff
            Offset to be added to obtain the final texel.

DESCRIPTION
    Performs a texture lookup in sampler *samp* using coordinates *s*, the
    coordinates used in the lookup are first projected, that is, divided by
    the last component of the coordinate vector and them used in the lookup.

PROFILE SUPPORT
    texCUBEproj is supported in all fragment profiles and all vertex
    profiles starting with vp40. Variants with integer samplers are only
    supported in gp4 and newer profiles.
