xbox: kill the ugly nv2a function prefixing
nv2a refactoring and a little more implementation
Why did I split these up again?
nv2a: basic texture shit. Still nothing works :(
nv2a: draw arrays command
nv2a: clear color
some minor nv2a non-fixes...
nv2a: cache shader constants to make gl trace less spamy
nv2a is uma!
