Commit Description:
Add timers for Simulation and various engines Starting to add additional timers for different stages of the process of updating in order to get more insight into what is slowing it down. The update takes 9ms, which is much longer than it used to. Engine-specific timers are coming later.

/* YUV-to-RGBA Effect
* Written by Ethan "flibitijibibo" Lee
* http://www.flibitijibibo.com/
*
* This effect is based on the YUV-to-RGBA GLSL shader found in SDL.
* Thus, it also released under the zlib license:
