- New version of the syntax rules from Michal Krol

   + Handles '1' as a float, just like '1.'
   + Remove switch collision between vp and fp #defines
   + result.color.xyz no longer requires result.color.primary.xyz

  *    Grammar Changes:
  *    -----------------------------------------------------
- *    - changed optional_exponent rule from:
- *         " exponent .or .true .emit '1' .emit 0x00;\n"
- *      to
- *         " exponent .or .true .emit '1' .emit 0x00 .emit $;\n"
- *
- *    - XXX: need to recognize "1" as a valid float ?
- *    - XXX: this fails:
- *               "MUL   result.color.xyz, R0, program.local[35] ;"
- *           but this works:        
- *               "MUL   result.color.primary.xyz, R0, program.local[35] ;"
- *             -> see progs/tests/arbvptorus.c
- *
- *    - changed "progLocalParam\n" changed from:
- *         " \"local\" .emit PROGRAM_PARAM_LOCAL .and lbracket .and progLocalParamNum 
- *                  .and rbracket;\n"
- *      to:                   
- *         " \"local\" .emit PROGRAM_PARAM_LOCAL .and lbracket .and progLocalParamNum 
- *                  .and rbracket .emit 0x00;\n"
- *      so we can distinguish between the progLocalParam and progLocalParams rules                  
- *
- *    - made the same change as above to the progEnvParam rule
