	* tile-cache.c
	* tile-private.h
	* tile.[ch]: removed trailing whitespace, added some newlines,
	let tile_is_valid() return a gboolean instead of a gint.

	* app/core/gimpimage-projection.c
	* app/core/gimpimage-undo-push.c
	* app/paint/gimppaintcore.c
	* app/tools/gimpinktool.c: use the return value from tile_is_valid()
	as a boolean.
