Someone on IRC just pointed out that GTK directly calls some X server
core functions that are in the process of being deprecated.  It was
suggested that GTK be rewritten to process all of its pixmap drawing
calls via Cairo.

torbenh4: so you call these functions "talking to X directly"
http://library.gnome.org/devel/gtkmm/stable/classGdk_1_1Drawable.html
torbenh4: its the legacy non-cairo drawing api. and most parts of gtk
itself still use it. not to mention lots of apps.
remi|work: torbenh4, it's not formally deprecated, but it's my
understanding that its use should be avoided

Cheers!
