 Hi guys

We finished (we hope) a really long effort to be such that we cannot 
have "negative" rectangles.
It implied fixing around 250 users of layoutFrame and a lot more.
We introduced point:point: to create rectangles.
We improved many little points.

We deeply tested the image but we never know it may happen that a layout 
policy produce strange rectangles again.
If you find some glitches we will fix them.

Stef and Igor
