you can use a GdkImage of type GDK_IMAGE_FASTEST. If possible it will
be created as GDK_IMAGE_SHARED (which means it uses Xshm). You can
then write your pixel data to the image and blit it to the
drawing_area using gdk_draw_image. That should be the fastest method
available if you need to draw pixel data. I wouldn't care too much
about the speed penalty of using GdkRGB however. It's pretty fast.
I'm not sure if there's a widget for DGA available. It's certainly not
part of the standard GTK+ distribution.
