NAME
    tex2DARRAYproj - performs a texture lookup with projection in a given
    sampler array.

SYNOPSIS
      float4 tex2DARRAYproj(sampler2DARRAY samp, float3 s)
      float4 tex2DARRAYproj(sampler2DARRAY samp, float3 s, int texelOff)

      int4 tex2DARRAYproj(isampler2DARRAY samp, float3 s)
      int4 tex2DARRAYproj(isampler2DARRAY samp, float3 s, int texelOff)

      unsigned int4 tex2DARRAYproj(usampler2DARRAY samp, float3 s)
      unsigned int4 tex2DARRAYproj(usampler2DARRAY samp, float3 s, int texelOff)

PARAMETERS
    samp    Sampler array to lookup.

    s       Coordinates to perform the lookup. The value used to select the
            layer should be passed as the component right after the lookup
            coordinates. 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 array *samp* using coordinates *s*,
    the layer used in the lookup is first selected using the coordinate
    component right after the regular coordinates. The coordinates used in
    the lookup are then projected, that is, divided by the last component of
    the coordinate vector and them used in the lookup.

PROFILE SUPPORT
    tex2DARRAYproj is only supported in gp4 and newer profiles.
