 * some minor movie cleanup, not what I would like but enough for now
 *
 * Revision 2.27  2005/10/16 23:15:46  wmcoolmon
 * Hardened cfile against array overflows
 *
 * Revision 2.26  2005/05/12 17:37:48  taylor
 * add an extra gr_flip() after gr_clear() to make sure the change is made active
 *
 * Revision 2.25  2005/04/24 06:52:23  wmcoolmon
 * Enabled movies in windowed mode; if this causes problems for people, they can always use -dnoshowvid

 * fix a few things post merge
 *
 * Revision 2.23  2004/11/27 10:42:18  taylor
 * this should get movies working again in D3D and help OGL too

 * Revision 2.22  2004/07/26 20:47:26  Kazan
 * remove MCD complete
 *
 * Revision 2.21  2004/07/12 16:32:43  Kazan
