Setting the Scaled property on the form did solve part of the problem.

1. Pixel of 48x48 now fits PictureBox of 48x48 on Debian 6.0.4

2. Form width of 1000 pixels now correctly fits within screen width of
1024 on Debian 6.0.4

3. Drawing text on a DrawArea still poses a problem on Debain 6.0.4
(see attached screens -> Ubuntu 10.10 -> text fits; Debian 6.0.4 -> text
goes beyond the DrawArea -> so doesn't fit)
I believe Ubuntu 10.04 having the same problem as Debian 6.0.4.

I build a small sample application where you can see the problem
yourself (depending on what distro you run it).
Any suggestions on how to solve this drawing text on a DrawArea?
