I'm working for providing well-defined, flexible, multi-platform OpenGL
extension API to GDK and GTK+. Much help is needed to achive this purpose.

As Owen and Josh said, current GtkGLExt-1.0 API has some add-on functions
which are awkward hacks for convenience. But they are just helper functions
to work closely with standard GDK/GTK+ and related libraries such as
libglade. Essential part of GtkGLExt (GdkGLConfig, GdkGLDrawable,
GdkGLWindow, etc.) really fit into the GDK/GTK+ manner. I'm sure that
current 1.0 API is not complete solution (I think best solution is
integrating GdkGLExt into GDK). I'll be willing to change current API in new
GtkGLExt-2.0 if people want.

So please tell me your opinion. Much help is wanted.

(Should GtkGLExt be developed on cvs.gnome.org?)
