I've made some tests in a emulator, about 2:1 ratio, and tuxpaint perfoms fine using all availabe space.
Re-reading the question seems they want to _discard_ some of the wide space in order to get a 16:9 ratio.

If that is what they want, they need to modify the fullscreen line to read something like
fullscreen=1600x900
then change the native line to
native=no
With that in place I get two black bands at each side of the tuxpaint window.



It is not obvious to manually change/edit the config file in Android, 
one must 'su' to the user who owns the tuxpaint.cfg file(u0_a153 in the case of my emulator) 
and edit the file as that user, so I don't expect any non rooted phone being able to do this.

Is it worth to extend the config tool to be able to cope with this requirement? 
Looks doable but it will take some time...

About the ticket at SF I was going to open it when I re-readed the message, 
I'd want to be sure I do not missunderstand the problem :)
