	* app/nav_window.c
	* app/nav_window.h
	* app/gimppreviewcache.h
	* app/layer.c
	* app/channel.c
	* app/commands.c

	Added some controls to the nav window. Yep. I know that the
	buttons are toooo biGGG.

	Preview cache changes. Now prime preview cache with a image
	so that later we have a better chance of a hit. Still
	needs to be more intelligent at doing this (needs to pick largest
	out of the cache & use its size as the size to prime with).
