NAME
    tex1Dlod - performs a texture lookup with a specified level of detail in
    a given sampler.

SYNOPSIS
      float4 tex1Dlod(sampler1D samp, float4 s)
      float4 tex1Dlod(sampler1D samp, float4 s, int texelOff)

      int4 tex1Dlod(isampler1D samp, float4 s)
      int4 tex1Dlod(isampler1D samp, float4 s, int texelOff)

      unsigned int4 tex1Dlod(usampler1D samp, float4 s)
      unsigned int4 tex1Dlod(usampler1D samp, float4 s, int texelOff)

PARAMETERS
    samp    Sampler to lookup.

    s       Coordinates to perform the lookup. The level of detail 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 a specified level of detail in sampler
    *samp* using coordinates *s*.

PROFILE SUPPORT
    tex1Dlod 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. Variants with integer samplers are
    also only suppported in gp4 and newer profiles.
