Let's initialize all LayoutFrame inst var to zero instead (empty layout).
This will provide the most reasonable default (the least surprising one).

This way we can continue using:
- (Layout offsets: aRectangle), and get an absolute layout.
- (Layout fractions: aRectangle), and get a pure proportional layout.

The goal is to expunge the nil protection out of the LayoutFrame.
Those nils are like additional states (to be or not to be nil...) and are gratuitous complexifications. We Ain't Gonna Need It anymore (the personal form of YAGNI).
