Bring back uniform to fill video scaling mode
From Trac https://trac.videolan.org/vlc/ticket/19517
On devices with the screen proportion other then 16:9 like Surface (3:2) or HP TouchSmart? (16:10) it is very useful to be able to fill screen with uniform scaling cropping parts off screen. Unfortunately this option was removed but I used it a lot. Please, bring it back.
