Added extra start frame to each chunk in the ChunkWriter and ChunkReader, to make sure every chunk can "stoke" the audio samples from the previous chunk. Also, added additional example code for an openshot::Frame.

Added license and copyright to all files. Improved many examples and documentation. Refactored the Coordinate() object, to move a few properties to methods.

Improved more documenation, and switched to @ syntax for doxygen.

Improved the timeline compositing performance, fixed some blackmagic bugs, and finally have an actual chromakey demo working!

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.

Added a simple chroma key method to a frame object, and added multi-threaded optimizations to the black magic capture code.

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.

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.

Added a new "smooth" slow motion, using the time map fraction to dissolve the next frame into the current one.

Fixed a huge memory leak related to cache objects, and incorrect frame sizes. It was caching way too many frames, and creating all sorts of issues.

Fixed a big bug on frame rate mapping, due to incorrect # of samples being copied into the new frame. Also, implemented interalacing support, and full pulldown support (in the frame mapper).

Many experimental changes, including a new FrameMapper that is based on FileReaderBase, and lots of debug code.

Fixed a regression with audio files and seeking, added a few new methods, and more accurately detect the End() of clips.

Another huge refactor and lots of big fixes! Time mapping now works... mostly. The jumpy / glitchy images have been solved by copying the AVFrame into an AVPicture, which does not get clobbered on the next decode.
...
Also, added a new frame number overaly (in the top, left part of the image), and a new AddColor() method, to change the size and color of the frame's image...
Padded the end of the FFmpegWriter / WriteTrailer() method, to avoid having a codec ignore the last many frames.

Major refactor to the cache object (again)! It now uses bytes to determine how many frames to keep.

Added a Rotate() method to a Frame object. Added new methods on a clip to translate frame numbers (FrameMapper and Time Curves). Now, the Timeline, Clip, and Readers are all working with animation curves. Pretty cool!

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.

Added a new ImageReader class, which uses ImageMagick++ to read image files, and produce openshot::Frame objects.

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.
