If we rely fromViews: methods on fromBase: et al, should we eliminate
the need to query a matrix from target view since they already have
native matrix to/from window stored?
Or is it better for rect conversion between 2 views with different
transforms so the result will enclose the target view's rect (ie. w/o
converting 3 points)? Or is that not necessary and the result should
just enclose the target's convertRectToBase: one, ie. I am not sure
why this is important if they are in different hierarchy.
