>Description:
	xli (xsetbg) can display image file with any zoom ratio.
	But if zoomed image is larger than display, it failed to clip it,
	because atx and aty overflow.
	I send a patch for the author one month before and he accept and agree
	with my patch, but he have not released bugfixed version.
>How-To-Repeat:
	fetch http://www.jp.FreeBSD.org/images/daemon1.jpg
	xsetbg -onroot -fullscreen daemon1.jpg (on 800x600 display)
