2.5

Requested UI feature: when scaling Blender window, the buttons view keeps
scale (in visible pixels) as previously. Also works for the .B25.blend, which
currently will show the buttons a bit too large for small screens... this 
because the .B25.blend was created on a 1920x1200 screen. Might need a config
inbetween... 1440x1080 or so? Or we make a couple of defaults later.

Additional feature could be to also scale the buttons area itself, but that
will change the entire screen layout too much, potentially giving bad issues
with extremer scaling.
