-/* 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:
- * -----------------------------------------------------
