Optimized the compositing of simple layers (with no transformation), by not resizing it's canvas to match the timeline. Also, improved the Decklink reader to wait for the frame to become available (if it's in the future), and to jump ahead on the timeline if it gets behind. Blackmagic program can now composite 4 layers in real time.

Made decklinkOutput keep scheduling the last successfull frame, if the queue runs out. Also, made the timeline multi-threaded, and improved the DecklinkInput.cpp to keep frames in order, by returning the correct frame based on the number.

Improved DecklinkReader to be multi-threaded, using the OpenShot cache object to keep things in order. Performance is very smooth on the blackmagic test executable now.

Adding the initial version of the decklink writer, and a fully working (full circle) blackmagic example executabe, which processes real-time HD video and output's it via HDMI.

Completed the DecklinkReader class, and improved the conditional black magic code to include SWIG. The Decklink reader fully works, multi-threaded, and looks good.

Refactored blackmagic capture example into DecklinkCapture.cpp, and added it into libopenshot. Also, added a new, Main_Blackmagic.cpp example program, which invokes the DecklinkCapture.cpp class.
Also, built in a 20 frame buffer into the DecklinkCapture.cpp class, to discard old frames, to keep the memory from filling up.

Fixed a big audio regression, with a buggy isnear() function, which did not take into account the amount of frames between the sample locations.

Fixed a big bug with the Swig wrapper, to correctly match the typemap of the tr1::shared_ptr, and then removed the GetFrameObject method, since it's no longer needed.

Made Keyframe objects thread safe, by generating the values as Points are added, and the Timeline's Open and Close logic was made thread safe, so a reader is not closed while it's still being accessed on another thread. Also removed some unneeded code and comments.

Fixed a really huge audio issue, related to audio timestamps, gaps, and also mono vs stereo issues. This is the best audio support I've accomplished thus far. =)

Added wave_color attribute to the clip object, which now allows the audio wave form to animate it's color along a curve over time. Combined with the timeline background color curve, some cool combinations can be made!

Refactored the audio waveform generation into the Timeline class. Added the ability to set the volume, and the ability to mix layers of audio samples together. Also, made the waveform's have a transparent background, so they can be layered on top of other layers.

Fixed a big audio bug, where varying timestamp values on low precision audio timebases (i.e. 1/1000) would leave small gaps in the audio wave. Also, fixed a few issues related to sample_rate getting lost between the reader and clip and timeline objects.

Updated the FFmpegWriter to use compiler #IF commands to be compatible with older and newer versions of FFmpeg. This is still a work in progress, but many of the newer commands are now being protected.
