Missing GL_LUMINANCE and GL_LUMINANCE_ALPHA ?

[carado]

Hi,

These bindings seem to be missing the two constants gl::LUMINANCE and gl::LUMINANCE_ALPHA.
I'm finding no reference to them on the docs.rs page and they don't seem to be working in my project.
From what I can tell, these constants have been in OpenGL since at least OpenGL 1.1, so I doubt it's a version problem.

Have a nice day !

I just noticed this as well.

Starting from OpenGL 3.3, they are only there if you enable compatibility mode when generating the bindings.

how can I enable compatibility mode?

I ran into this because LUMINANCE and LUMINANCE_ALPHA are still the only non-deprecated one and two channel formats for OpenGL ES. They should be generated even without compatibility mode because for ES compatibility.
