[GtkGLExt] What's the difference between GtkGlExt's own buffer-swapping and Gdk's ...

[Jack Chen <jacks_small_world yahoo com>]

Hi, I have a question.

What is the difference between GtkGlExt's front-back-buffer-swapping in
double buffering mode, and Gdk's method by creating the GdkPixmap
first, rendering an image to the pixmap, then copying the data in the
pixmap to the widget->window?

Thanks in advance for the reply.

Jack
