[MC-890] Flickering pig when riding

When looking forward at certain angles the pig will flicker rapidly. This also used to happen to minecarts though those seems to be fixed.

Demonstration in attached video clip.

Environment

Java 7 64-bit, Win7 64-bit

See also [MC-191], maybe it's a generic issue with ridden entities ?

Yeah that's definetly the same issue, didn't think of looking backwards in the minecart when testing it myself lol.
