I haven't checked your changes yet (just reading ChangeLog) but
invalidating the maskee itself should not be necessary. The
invalidation stuff is only about finding the stage *area* that has to
be re-rendered.

The mask and the maskee by nature are on "top of each other". So, when
invalidating the mask you implicitely force also re-rendering of the
maskee.

It's like when a sprite instance A, which has a child (instance B)
toggles it's visibility state: this doesn't affect (invalidate)
instance B but will trigger rendering of it anyway.

As always, it's important to call set_invalidated() *before* the mask
changes (or becomes a mask).

The attached file is not related to setMask() but still shows a
changing mask with a fixed maskee. Only the mask area gets
invalidated.
