	Contains:	Functions to enable building and destorying a DSp fullscreen context

	Written by:	Geoff Stahl (ggs)

	Copyright:	Copyright <EFBFBD> 1999 Apple Computer, Inc., All Rights Reserved

	Change History (most recent first):

         <2>     3/26/01    ggs     Add DSp version check and other items for full screen on X
         <1>     1/19/01    ggs     Initial re-add
         <4>     1/26/00    ggs     Add fade code back in, ensure NULL pointer/context checks are in
         <3>     1/24/00    ggs     Add C++ support
         <2>    12/18/99    ggs     Fix headers
         <1>    11/28/99    ggs     Initial add.  Split of just DSp handling functions.  Added total
                                    device RAM checks, better step downs using actual supported
                                    resolutions. Need to add user verify for contexts that require
                                    it, integration of this in context step down, and a freq bit
                                    field.
         <1>    11/11/99    ggs     Initial Add
