refactored all memcpy into (multithreaded) frame copy, refactored all memset into (multirheaded) frame clear, multithreaded super and sub sampling (only tested 4:2:2 ), added new mode to pencil sketch, fixed bug in lens correction, multithreaded 36 effects, updated minilzo to newer version, multhreaded yuv functions for format conversion and pixel scaling, multithreaded fx chain fader, multithreaded fx apply in libvje. Fix bug in encoder when recording in high resolution,
