Did not bother to research long enough
Thats also why i called it a hack, hehe.

Hmm there are really drivers which export foo and not foo ?
Logically i find exporting only foo more plausible than exporting only foo.
Anyways, i fixed it, and my hack should cover both cases, im quite happy with it
Regarding the performance issues i have, i found out that the fixed pipeline emulation shader used is terribly slow on the POWERVR SGX used in the iPhone.
It uses discard which is a big nono accoring to PowerVR specs, commenting out all discard instances and disabling lightning calculation puts me up to 25-30 fps.
