Do anyone knows what GL_NV_extended_combiner_program is for? (listed in the NV30 emulation mode)

High precision register combiners ?

i don’t think they are higher precision, the high precision part is before the rc’s, namely the nv_fragment_program… but i’m interested anyways, what new bulky proprietary ext nvidia presents us there. espencially some register combiner ext (i love them… (no, that was not sarcasm… they are fun to work with ))

we’ll see what it is when some specs have it documented… anyone yet found one?
