2/** @file
3 * VirtualBox X11 Additions graphics driver X server helper functions
4 *
5 * This file contains helpers which call back into the X server. The longer-
6 * term idea is to eliminate X server version dependencies in as many files as
7 * possible inside the driver code. Ideally most files should not directly
8 * depend on X server symbols at all.
