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.

Fix glDrawElements + VBO rendering when ptr/offset is not zero.

When an index VBO is bound, glDrawElement's indices pointer is really an
offset into the element buffer. Add that offset to the prims[i].start
