minecraft-pe-0.6.1/src/client/renderer/entity/EntityRenderer.cpp
Shredder 055f00be49 A bit big of a commit but 
Added 3 Fog Choices (Pocket) (Java) (Unknown that was unused)

Restored Java Beta Sky Color code that was unused that depends on biome temperature (choosable using Java fog)

Tile Shadows and Entity Shadows that appear beneath them have been restored and fixed from the unused code, toggleable by turning fancy graphics on or off

Entities will now render flames on themselves when on fire, including the player

Added option to use Java Style Item Count text and position in tweaks
