-Notes on program parameters, etc.
-
-The instructions we emit will use six kinds of source registers:
-
-  PROGRAM_INPUT      - input registers
-  PROGRAM_TEMPORARY  - temp registers
-  PROGRAM_ADDRESS    - address/indirect register
-  PROGRAM_SAMPLER    - texture sampler
-  PROGRAM_CONSTANT   - indexes into program->Parameters, a known constant/literal
-  PROGRAM_STATE_VAR  - indexes into program->Parameters, and may actually be:
-                       + a state variable, like "state.fog.color", or
-                       + a pointer to a "program.local[k]" parameter, or
-                       + a pointer to a "program.env[k]" parameter
-
-Basically, all the program.local[] and program.env[] values will get mapped
-into the unified gl_program->Parameters array.  This solves the problem of
-having three separate program parameter arrays.
