Use shared memory images when shared pixmaps are not available.
Modern graphics drivers tend to disable shared memory pixmaps,
since rendering operations often can't be accelerated by the
GPU when the pixmap data is pinned in system RAM.
Use XShmPutImage() to flush the window surface when this is case,
instead of falling back to the slower XPutImage() method.
