The new fadeInOut state property lets you specify fade properties that are common to both the fade-in phase (i.e. when mousing over a node) and the fade-out phase (i.e. when mousing out of a node) of the hover fade effect.

The reverse fade property now has special handling in the context of the Uize.Widget.HoverFader class.

When specifying the value true for the reverse fade property, the Uize.Widget.HoverFader class swaps the values that it would normally use as the start and end values of the style fade for a node. This has the effect of only reversing the transition effect, but not the start and end style. This becomes more pronounced - and more compelling - when compound values are specified for the curve fade property, where reversing the effect of the curves produces interesting results.

The tickle instance method has been improved with support for a new variation that takes a fadePropertiesOBJ parameter.

By specifying fade properties instead of an interval when calling the tickle instance method, it is possible to achieve non-linear "tickling" of the nodes of an instance. One can use the curve fade property so that the timing of the triggering of the fade-outs for the different nodes of the instance is not uniform. In addition, one can use the reverse fade property to control the order in which the tickling occurs, where specifying the value true will cause the tickling to start with the last node and end at the first node.
