Hmmm, the spec says internalFormat should be a GLint but SGI's
glext.h file has GLenum.  Also, the gl.spec file (which is used
to generate glext.h and other files) uses the PixelInternalFormat
type which in all other functions maps to GLenum.

Looks like an inconsistency in the gl.spec file.  I'll contact SGI.
