/* The purpose of this program is to show how to create a widget for producing
 * video output from your workstation display (that is, taking a portion of the
 * display and producing a video signal that can be viewed on a TV monitor,
 * VCR, or other such device).
 * The program creates a top-level shell and a VideoOut widget.  A rectangle
 * is used for hard-coding the area of the screen to be captured.

/* 
 * Revision 1.12  1997/09/17  09:30     schmitz
 * Fixed this to run under Overlay libraries;  Need to 
 * Create In widget, and point out widget source window
 * to the input widget window
 *
 * Revision 1.11  1995/04/01  01:19:11  lovvik
 * Fixed the problem where xvOutTest does not turn on output
 * until the user resizes the window.  It turns out that you
 * must perform the XtVaSetValues after entering XtMainLoop().
 * This would not normally be an inconvenience because the
 * code that is now in VideoOutputOn() would appear in a
 * callback function for a button press.
 *
 * Revision 1.10  1993/09/10  12:37:39  drapeau
 * First public version of this test program.
