minecraft-pe-0.6.1/src/client/renderer/entity/EntityRenderer.cpp
Shredder 890604256b Fixes and New Additions 
Added GUI Styles with 3 options: Java, Pi/Xperia and Pocket

Hopefully fixed touch input eating and breaking blocks bug

Fire should render on all mobs now

Fixed only one side of the first person burning animation being animated

Added Window Scaling Option for PC Users (Hasn't been tested on other platforms

Render Distance is now configurable from the settings menu

Tried to fix shadows again on IOS and Android, hopefully works?

Block Outline Selection now has a thicker outline for better visibility
