Uhmmm... That's just about right. But I think GtkGLExt and GtkGLArea
wouldn't be in conflict with each other.

GtkGLExt could provide the GDK drawing infrastructure for OpenGL
rendering which follows the GLX interface...

   < GDK >              < GLX >
  GdkGLConfig    <-->  GLXFBConfig
  GdkGLContext   <-->  GLXContext
  GdkGLDrawable  <-->  GLXDrawable
  GdkGLPixmap    <-->  GLXPixmap
  GdkGLWindow    <-->  GLXWindow

On the other hand, GtkGLArea could provide a GTK+ widget for
displaying OpenGL scene which likes GLw.

  GtkGLArea      <-->  GLwDrawingArea

I hope these two projects cooperate with each other ;-)
