+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.
