Bug fix for the model-free analysis tab about window - sometimes a grey region would appear at the bottom.

This is a problem in at least GTK+ as scrolling is in increments of 20!

Bug fix for sizing of the GUI about dialogs - the virtual sizes are now accurately calculated.

A space is also now added to the end to ensure the border is there.

Improved the debugging drawing for the about GUI elements.
