Subject: More GLSL code: - use macros to access and modify render inputs
 bit-field; - un-alias generic vertex attributes for ARB vertex calls; - use
 MAX_VERTEX_PROGRAM_ATTRIBS (NV code) or MAX_VERTEX_ATTRIBS   (ARB code) in
 place of VERT_ATTRIB_MAX; - define VERT_ATTRIB_GENERIC0..15 for un-aliased
 vertex   attributes for ARB_vertex_shader; - fix generic attribute index
 range check in arbprogparse.c; - interface GLSL varyings between vertex and
 fragment shader; - use 64-bit optimised bitset (bitset.h) for render inputs;
