NAME
    tex2Dcmpbias - performs a texture lookup with bias and shadow compare in
    a given sampler.

SYNOPSIS
      float4 tex2Dcmpbias(sampler2D samp, float4 s)
      float4 tex2Dcmpbias(sampler2D samp, float4 s, int texelOff)

PARAMETERS
    samp    Sampler to lookup.

    s       Coordinates to perform the lookup. The value used in the shadow
            comparison should be passed right after the normal coordinates.
            The bias value 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 with shadow compare and bias in sampler *samp*
    using coordinates *s*.

PROFILE SUPPORT
    tex2Dcmpbias is supported in fragment profiles starting with fp40 and in
    vertex profiles starting with vp40. Variants with *texelOff* are only
    supported in gp4 and newer profiles.
