Tile root pixmap in the glx backend
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 Signed-off-by: Yuxuan Shui <yshuiv7@gmail.com>
