/*
 * xvdisp.c
 *
 *   xv automatically downscales if necessary, to display the entire
 *   image without scrollbars.  Because xv downscaling is suboptimal,
 *   the image looks worse than it will actually look using our
 *   area mapping downscaling.
 *
 *   With xvdisp, we do the scaling, if necessary, and launch xv on
 *   the downscaled image.
