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

To do this, the window contents (a wx.BufferedDC instance) is created twice, 
with the virtual window
size exactly calculated in the first pass, and then used to set up the device 
context in the second.
A space is also now added to the end to ensure the border is there.
