Ken,
Assuming the caches don't completely derail things, you ought to be
able to make this work with pretty minimal impact:
- Keep the low four bits of the sampler index where they are
- If the 5th bit is set:
- Force message header on
- Add 16*sizeof(sampler_state) to the copy of r0.3 in

Which is the problem. The method we're using to access samplers works
fine for up to 16, but
The test seems to work correctly with 32 textures per stage. It tests
that all textures return the correct color, but the sampler state is
always the same.

Oh, wow. No...no, it can't possibly work then. (Apparently

Sampler messages' descriptor only has 4 bits for the sampler index, so
it seems you'd silently lose the top bit and get the wrong sampler
parameters.

This causes us to advertise:
- GL_MAX_TEXTURE_IMAGE_UNITS = 32
- GL_MAX_VERTEX_TEXTURE_IMAGE_UNITS = 32
- GL_MAX_COMBINED_TEXTURE_IMAGE_UNITS = 96
instead of the old values of 16, 16, and 48.
