NAME
    tex1DARRAY - performs a texture lookup in a given sampler array may use
    pre computed derivatives and, in some cases, perform a shadow
    comparison.

                        int texelOff)
      float4 tex1DARRAY(sampler1DARRAY samp, float3 s, float dx, float dy)
      float4 tex1DARRAY(sampler1DARRAY samp, float3 s, float dx, float dy,

                      int texelOff)

      unsigned int4 tex1DARRAY(usampler1DARRAY samp, float2 s)
      unsigned int4 tex1DARRAY(usampler1DARRAY samp, float2 s, int texelOff)

      unsigned int4 tex1DARRAY(usampler1DARRAY samp, float2 s, float dx, float dy)
      unsigned int4 tex1DARRAY(usampler1DARRAY samp, float2 s, float dx, float dy,

PARAMETERS
    samp    Sampler array to look up.

    s       Coordinates to perform the lookup. The value used to select the
            layer is passed immediatelly after the regular coordinates, if
            an extra coordinate is present it is used to perform a shadow
            comparison.

    dx      Pre computed derivative along the x axis.

    dy      Pre computed derivative along the y axis.

    texelOff
            Offset to be added to obtain the final texel.

DESCRIPTION
    Performs a texture lookup in sampler *samp* using coordinates *s*, the
    texture to be sampled is selected from the layer specified in the
    coordinates. Also may use the derivatives *dx* and *dy*, the lookup may
    involve a shadow comparison and use texel offset *texelOff* to compute
    the final texel.

PROFILE SUPPORT
    tex1DARRAY is only supported in gp4 and newer profiles.
