Why, when the current XLib already uses XCB. The current XLib
implementation is not a "pure" xlib any more, it is more like a
wrapper for XCB (at least that is so under Linux). I've wanted to
implement a pure XCB backend for fpGUI too, and after doing some
research I found about the Xlib wrapper over XCB under Linux.
Just take a look at an fpGUI application compiled with XLib as
backend. Note the dependency in libxcb.so in the list, yet I did not
use XCB at all in fpGUI.

I wouldn't waste my time on XCB. XLib is not going to disappear. Plus
Wayland is on it's way, which means you would probably have to change
to that anyway.
