Note that in the end, we just have the same problem that we have today 
when the user choose directly width and height.
The user will choose a zoom factor, left/right border and you will get 
the width (same for height).

I don't see what is bothering you ? Selecting borders separatly will 
also yield to a total width and height, so we can apply the same code we 
have today.

In all the case, I intend to have an internal screen of approx 460x276 ; 
if the SDL screen is bigger that that, we add extra black pixels

That was just a comparison to show the different size of each border. I 
think zoom and border size (that is all parameters that define the size 
of the window you get on screen) should stay together.


I don't have much time to look at the options window layout I would need 
for now, if you want to commit your falcon changes, go for it, we can 
add other options later (I still need to write the code first :) )
