Re-implement GLSL texture sampler variables.
GLSL sampler variables indicate which texture unit to use for TEX instructions.
Previously, this was baked into the fragment/vertex program and couldn't be
readily changed once set.
Now, SamplerUnits[] array indicates which texture unit is to be used for
each sampler variable. These values are set with glUniform1i().
This is extra state that must be passed to the fragment/vertex program
executor at runtime.
