Added a new experimental overlay method to a frame, which composites images from multiple frames, and adds the result to the bottom right side of the image.

Enabled multi-threading decoding and encoding with libavcodec, setting the thread_count property. This make a huge improvement in CPU performance, for codecs that support this property.

Fixed a big regression where the "omp" tag was not correct. Also, restructured the encoder to be much faster, and changed "omp master" to "omp single".

Added pool of software image scalers to the FFmpegWriter / encoder, and removed OMP critical section. Also, refactored some audio and video codecs, and changed "resize" to "scale" for speed improvements.

Fixed a huge bug where the FFmpegWriter was not scaling colors to 8 bit, and that would crash on certain colors being used in an image. Also, added a new, experimental waveform visualization to the encoder.

Huge refactor, switched almost all methods to using pointers for Frames, and moved some key method calls outside the critical OMP sections. Also, refactored the sws scaler, to create a pool of 32 scalers, and give each thread it's own scaler. This refactor resulted in a 40%+ increase in speed on the FFmpegReader class.
I also added a cmake build flag for the google perftools library, to assist on profiling performance issues.
