	You want to isolate a simple test case from eog's icon rendering ? if
so - you need to do some code reading. Personally I would follow these
steps:

	* first - create a minimal gtk+ app to render a button
	  with an icon - I would do that by running 'gtk-demo' which
	  has source for you to steal.

	* then include <gdkx.h> and start cut/paste/in-lining the
	  relevant code from gtk+/gdk/x11/ that does the image
	  handling

	Quite possibly the problem is related to Xrender support; which we use
for rendering icons, primarily because this off-loads the alpha blending
into the Xserver (and theoretically hardware), and saves round-trips. I
would suspect XRenderCreatePicture / XRenderComposite myself.

	ATB,
