The "font size hell" comes from the fact that the screen DPI returned by 
X-window is often false.

So I decided that all screen font size will be internally modified so that the 
screen resolution is always 96 DPI. This is the mean of the Font.Resolution 
property. The Desktop.Resolution property returns what X-Window says about 
your screen.

I put the line 'Application.Font = Font["10"]' in the source code, so that 
forms display the same everywhere. This is stupid, as I should only did that 
in the form windows. And I'm going to do that now... :-)

If you change Font.Resolution in your code, or if your default desktop font 
size is not 10, then when you run the program, the font size will be 
different from what you see in the form editor.

I did all that so that when you make a GUI with Gambas, you are almost sure 
that this GUI will look the same on another computer/screen...
