component right after the lookup coordinates. The value used in the projection should be passed
as the last component of the coordinate vector. The value used in the shadow comparison, if
present, should be passed as the next-to-last component of the coordinate vector.

<P>
Performs a texture lookup in sampler array <I>samp</I> using coordinates <I>s</I>, 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. If an extra coordinate is present it is used
to perform a shadow comparison, the value used in the shadow comparison is always the next-to-last
component in the coordinate vector.
