[Bf-committers] Panel auto resize bug

Nope, the HOME key scales, and automating this will be extremely  
annoying with context switching. For example; having only 2 panels in  
view, go to editmode, and suddently have 5 panels. Or: when you  
collapse a few. Scale really has to be fixed.

The purpose is to find a method that you only once initialize the  
windows, either vertical or horizontal, and after that you should have  
no need for further 'home key' pressing. If you like buttons small,  
they stay small. When panels dont fit in the available space, you can  
use mouswheel and pageup/pagedown to view them all. Or collapse one or
