Alright, thanks Sam, i'll list the properties of the root window and
see what I can pick from there.

[This is a nightmare. Maybe I should abandon XCB and switch to GTK or
Qt, but how do people deploy apps (in binary form) with these toolkits
on Linux? Do they ship these 50MB monsters with their apps? Or do they
dump the problem on the user? Or do they link them statically for less
bloat? But then do they have to provide a downloadable/buildable
source-kit for LGPL compliance? Sorry if these questions are too
general for this list (is there a better list? I need a
linux-gui-app-developers-list)]
