* 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.
