* These escapes let the SVGA driver provide optional information to

* 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.
