-/* TODO:
- *    Fragment Program Stuff:
- *    -----------------------------------------------------
- *
- *    - things from Michal's email
- *       + overflow on atoi
- *       + not-overflowing floats (don't use parse_integer..)
- *       + can remove range checking in arbparse.c
- *
- *    - check all limits of number of various variables
- *      + parameters
- *
- *    - test! test! test!
- *
- *    Vertex Program Stuff:
- *    -----------------------------------------------------
- *    - Optimize param array usage and count limits correctly, see spec,
- *         section 2.14.3.7
- *       + Record if an array is reference absolutly or relatively (or both)
- *       + For absolute arrays, store a bitmap of accesses
- *       + For single parameters, store an access flag
- *       + After parsing, make a parameter cleanup and merging pass, where
- *           relative arrays are layed out first, followed by abs arrays, and
- *           finally single state.
- *       + Remap offsets for param src and dst registers
- *       + Now we can properly count parameter usage
- *
- *    - Multiple state binding errors in param arrays (see spec, just before
- *         section 2.14.3.3)
- *    - grep for XXX
- *
- *    Mesa Stuff
- *    -----------------------------------------------------
- *    - User clipping planes vs. PositionInvariant
- *    - Is it sufficient to just multiply by the mvp to transform in the
- *        PositionInvariant case? Or do we need something more involved?
- *
- *    - vp_src swizzle is GLubyte, fp_src swizzle is GLuint
- *    - fetch state listed in program_parameters list
- *       + WTF should this go???
- *       + currently in nvvertexec.c and s_nvfragprog.c
- *
- *    - allow for multiple address registers (and fetch address regs properly)
- *
- *    Cosmetic Stuff
- *    -----------------------------------------------------
- * 	- remove any leftover unused grammer.c stuff (dict_ ?)
- * 	- fix grammer.c error handling so its not static
- * 	- #ifdef around stuff pertaining to extentions
- *
- *    Outstanding Questions:
- *    -----------------------------------------------------
- *    - ARB_matrix_palette / ARB_vertex_blend -- not supported
- *      what gets hacked off because of this:
- *       + VERTEX_ATTRIB_MATRIXINDEX
- *       + VERTEX_ATTRIB_WEIGHT
- *       + MATRIX_MODELVIEW
- *       + MATRIX_PALETTE
- *
- *    - When can we fetch env/local params from their own register files, and
- *      when to we have to fetch them into the main state register file?
- *      (think arrays)
- *
- *    Grammar Changes:
- *    -----------------------------------------------------

-- check the program string for '\0' characters
-- copy the program string to a one-byte-longer location to have
