always return channel->x1,y1,x2,y2, *not* tx1,ty1,tx2,ty2 since the latter 

2003-06-05  Michael Natterer  <mitch@gimp.org>

	* app/core/gimpchannel.c (gimp_channel_bounds): always return
	channel->x1,y1,x2,y2, *not* tx1,ty1,tx2,ty2 since the latter
	contain bogus values if the mask is empty. Fixes bug #114419.

	* plug-ins/script-fu/scripts/unsharp-mask.scm: cleaned up
	while searching the bug.
