Please consider the first (and unapplied) DrawPrim() patch #1/9.

Subject: [PATCH 2/9] Add the bulk of the GLSL string generation functions
- Add a new file glsl_shader.c which contains almost every GLSL specific function we'll need
- Move print_glsl_info() into glsl_shader.c
- Move the shader_reg_maps struct info into the private header, and make it part of SHADER_OPCODE_ARG.
- Create a new shared ps/vs register map for float constants (future patch will make ARB programs use this, too)
- This is a big patch, but none of the new functions in glsl_shader.c are being called yet. This just sets them up.
- This should be a no-op for users.
