Mozilla's Xlib toolkit has support for XIE... and maybe the (default)
GTK+ toolkit for Mozilla get it's XIE support back since this gives a
huge speedup for image scaling/blending on platforms who still have XIE
support available by default (I am looking here at Solaris/Xsun :) ...
PEX can (IMO) be removed... but if you remove XIE it would be nice to
provide an alternative which supports things like image scaling,
rotation and blending (RENDER doesn't count - it's broken by design...
