From decompiling the two GnmDriver libraries, it seems like sceGnmDrawInitToDefaultContextStateInternalCommand inlines a call to sceGnmDrawInitToDefaultContextState, so I've replaced that with an actual call to the function for readability.
sceGnmDrawInitToDefaultContextStateInternalSize is one to one with decomp.
