NAME
    texBUF - performs an unfiltered texture lookup in a given texture buffer
    sampler.

SYNOPSIS
      float4 texBUF(samplerBUF samp, int s)

      int4 texBUF(isamplerBUF samp, int s)

      unsigned int4 texBUF(usamplerBUF samp, int s)

PARAMETERS
    samp    Sampler to lookup.

    s       Coordinates to perform the lookup.

DESCRIPTION
    Performs an unfiltered texture lookup in texture buffer sampler *samp*
    using coordinates *s*.

    Texture buffer samplers are created with the EXT_texture_buffer_object
    extension. See:

      http://developer.download.nvidia.com/opengl/specs/GL_EXT_texture_buffer_object.txt

    Texture buffer object samplers roughly correspond to the *tbuffer*
    functionality of DirectX 10.

PROFILE SUPPORT
    texBUF is supported in gp4vp, gp4gp, and gp4fp profiles.
