integrate new AVAnimatorOpenGLView view renderer for use with CoreVideo pixel buffers from a h264 asset decoder, rework defines in AVAssetConvertCommon.h so that asset or core video texture support is compiled out if too early a version of iOS is targeted, reimplement AVAssetFrameDecoder so that it works as a realtime source for video frames when the produceCoreVideoPixelBuffers flag is set, support skipping over frames in the h264 decode logic, add basic test cases, set min target to iOS 5.0 for both the app and regression test targets, link GLKit and OpenGLES frameworks
