-wxPython/Tools/img2py.py for the implementation. Unfortunatly, there
-is no SaveFile implemented for the XPM image type in wxGTK so the
-tools to create the embedded image files don't work on wxGTK, only on
-wxMSW. The img2xpm.py tool could probably be hacked to use external
-tools, or PIL, to do the XPM conversion on wxGTK. If somebody does
-this please send me a patch.
