ARB_texture_storage reported as unsupported if EXT_direct_state_access is not present #15

Open aejsmith opened 9 years ago

GLEW is reporting ARB_texture_storage as unsupported on OS X 10.9, even though it is. Upon further inspection it looks like it's doing so because the EXT_direct_state_access functions included in the extension aren't implemented.

Since the ARB_texture_storage spec only specifies those functions to exist when EXT_direct_state_access is present as well, I don't think GLEW should be marking the whole extension as unsupported in this case.

Yes, agreed. GLEW support for DSA has been a problem area.

Still looks like a legit issue:
