X11 backend

Simon Ser requested to merge github/fork/ascent12/x11-backend into master

Created by: ascent12

An X11 backend. It's deliberately been written to be pretty basic. I don't really care enough to write something fancy for this.

There is a segfault that sometimes happens when you click on a blank examples/compositor. I don't really know enough about that code to fix it.
