* clutter/clutter-behaviour-depth.c: Clarify that what drives
	the movement along the Z axis is the ClutterAlpha object (we
	don't have the luxury of a rollover like the opacity does);
	so, if you want to go from 0 to -100 you have to use a
	decreasing function, just as well if you want to go from 100
	to 0. Using a min-depth of 100 and a max-depth of 0 and an
	increasing function is undefined behaviour.

	* tests/Makefile.am:
	* tests/test-depth.c: Add a test case for the depth behaviour.
