I guess you mean the code defined in
http://w3.org/mid/abd6c80105070617165f3f9813@mail.gmail.com

The fact that CanvasWidth and CanvasHeight are defined outside 
Form1() constructor makes it harder to decipher the fact out of the 
code. Adding a couple of comments wouldn't be too bad.

I'll try to explain this in my own words and we'll see if you agree 
with my interpretation.

All regions are computed as [left|top|width|height]Growth was zero. 
Then a bounding box containing all regions is computed to get canvas 
size (I'd prefer this method to compute the canvas size even though 
you used hardcoded canvas size in your example implementation - this 
guarantees no extra whitespace around the layout). Then the 
*remaining space* (sounds a bit like %%-unit, doesn't it?) is shared 
between different regions according to [left|top|width|height]Growth.

Is this a correct interpretation?
