Quads use VBOs instead of display lists. GLSL program objects are generated using modern APIs. Shader packages generated using reader/writer objects for serializing/de-serializing directory of shaders. Refactored shader unit classes to use the new classes. Refactored the shaders mediator class to use the new shader units. View animation code refactored from the controller object into self-contained classes. View classes refactored into a more descriptive hierarchy. Now using Xcode 4.6 and the new llvm compiler.

Fixed an issue with shader units that caused an OpenGL error.

Demonstrates adding of effects & filters to QuickTime Movies in realtime using GLSL shaders and the Core Video texture pipeline.
