program is enabled AND the currently bound program is valid.
Check _Enable instead of Enable to prevent things from blowing up
when someone calls glEnable(GL_VERTEX_PROGRAM_ARB) without actually
defining a program.

Some need to be set per-vertex, other per-primitive. Cleared that up.
Only need to init temp/result registers if executing an NV vertex program.

Some texture instructions were using wrong LOD.
Fixed interpolate_texcoords() so it doesn't do texcoord projective division
when using a fragment program. The TXP instruction does that.

Be sure to assign program.Base.String pointer.

Sounds good :)

Needs testing - it havent been even compiled yet.

TODO:
- add checking for duplicate symbols (or is it done already?)
- move all the statics (grammar objects list and last error message)
to the GL context state; I think simple pointer initialized in a
first call to ProgramString() is sufficent.
- apply an optimized version of match() - this will be needed for
glslang compiler.
