scaleUnitSquareToSize: does not appear to behave the same as native Objective-C version

[enquora]

Reductions attached in both Objective-C and Objective-J.
Objective-J version behaves differently, as demonstrated by both Javascript console and crash.
Scaling Tests, Native and Cappuccino.zip

Note the manual test produces expected behaviour but uses a static superview.
This reduction places the scaled view in a resizable window and changes the unitSquare dynamically.

@didierkorthoudt Would you mind trying both the native example and the Cappuccino one using your most current Aristo3 branch? It shouldn't take more than 5 minutes - resize the window and note the behaviour.

We appear to use CSS to manage scaleUnitSquareToSize:. I'm curious whether the same behaviour I'm seeing is still present with the theming changes you've made (so far) in Aristo3.

Note: the existing manual scaling test does result in expected behaviour, but seems to test only a subset of possible usages.

@enquora we should add your reduction to the ManualTests. can you please make a PR for this?
