QOpenGLExtraFunctions is missing glGetTexImage

[kitfox]

I've used OpenGL to render an image to a texture and want to dump it to disk. OpenGL defines several function for doing this including glGetTexImage which has been in the standard since at least 2.0, but these functions are completely missing from the Qt OpenGL wrapper. I'm a little stuck as to what to do.

Is there a way to use the OpenGL library directly in my program without having to use the Qt wrapper?

You're most likely looking for QAbstractOpenGLFunctions.
