Tile root pixmap in the glx backend

Browse Source 
In X, background pixmap is tiled (meaning they are repeated to filled
the window) by default. So, in the glx backend, we mimic this behavior
by binding the background pixmap of the root window (aka, the wallpaper)
to texture that repeats.

Fixes #107
