+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.

+; DO NOT EDIT - This file generated automatically by mesadef.py script
+;DESCRIPTION 'Mesa (OpenGL work-alike) for Win32'
+VERSION 6.5
+;
+; Module definition file for Mesa (OPENGL32.DLL)
+;
+; Note: The OpenGL functions use the STDCALL
+; function calling convention. Microsoft's
+; OPENGL32 uses this convention and so must the
+; Mesa OPENGL32 so that the Mesa DLL can be used
+; as a drop-in replacement.
+;
+; The linker exports STDCALL entry points with
+; 'decorated' names; e.g., _glBegin@0, where the
+; trailing number is the number of bytes of
+; parameter data pushed onto the stack. The
+; callee is responsible for popping this data
+; off the stack, usually via a RETF n instruction.
+;
+; However, the Microsoft OPENGL32.DLL does not export
+; the decorated names, even though the calling convention
+; is STDCALL. So, this module definition file is
+; needed to force the Mesa OPENGL32.DLL to export the
+; symbols in the same manner as the Microsoft DLL.
+; Were it not for this problem, this file would not
+; be needed (for the gl* functions) since the entry
+; points are compiled with dllexport declspec.
+;
+; However, this file is still needed to export "internal"
+; Mesa symbols for the benefit of the OSMESA32.DLL.
