xlib test case

Here's a slightly more minimal test case. It uses only cairo and Xlib, not
GTK+. And it continuously redraws so there's no need to drag another window
over the program's window to see the bug.

Note: Dragging windows, or otherwise keeping your X server busy, does make the
bug manifest itself more regularly. If I leave my X server pretty much alone,
this test case stops triggering the bug, (instead of sweeping, miscolored
lines, the window contents become static).
