 * These escapes let the SVGA driver provide optional information to
 * he host about the state of the guest or guest applications. The
 * host can use these hints to make user interface or performance
 * decisions.
 *
 * Notes:
 *
 *   - SVGA_ESCAPE_VMWARE_HINT_FULLSCREEN is deprecated for guests
 *     that use the SVGA Screen Object extension. Instead of sending
 *     this escape, use the SVGA_SCREEN_FULLSCREEN_HINT flag on your
 *     Screen Object.
