3.00.01 - Round image timing to nearest 10ms instead of truncating. Insert 

Tue Mar 30 20:50:21 BST 1999  Adam D. Moss  <adam@gimp.org>

	* plug-ins/gif/gif.c:
	3.00.01 - Round image timing to nearest 10ms instead of
	truncating.  Insert a mandatory 10ms minimum delay
	for the frames of looping animated GIFs, to avoid
	generating an evil CPU-sucking animation that 'other'
	GIF-animators sometimes like to save.
