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.

Integrated sub-pixel positioning using the distort operator. Not quite working yet.

The timeline classes are finally working correctly, and have the following features:
...
1) Layers (unlimited # of layers)
2) IN, OUT, and Position (time)
3) X, Y offset
4) Alpha
5) Rotation
6) Transparency + compositing + overlays

Integrated more timeline code, such as compositing layers... but they don't work yet

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

Fixed a problem with audio time map deltas, and being slowed down instead of sped up

Fixed the FFMpegReader to discard the first audio and video frames it finds after a seek, since they sometimes are missing information. This fixed many issues with the time mapping curves and audio reversing and fast forwarding.

FIxed some big audio bugs, and finally got the audio reversing correctly working. Now, audio waves are reversed when a time map is moving backwards. There are still some pops and crackles, but I'll fix those later.

Added some new methods on the keyframe class, and added some unit tests for the keyframes.

Fixed some bugs with the new Keyframe system, and now it generates the correct values.

Improved the Keyframe and Coordinate classes, to also track the direction and a fraction representing the number of times a frame is repeated. This will allow the time mapping to slow down audio and reverse the waveforms when necessary.

Added some experimental time mapping code, to resample slow or fast audio samples.

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

Yet another huge refactor, to use shared_ptr objects instead of actual pointers, due to the difficulties in managing the lifecycle of pointers between the timeline, clip, and readers. Seems to work great, and solves all sorts of bugs. =)

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.

Refactored seek method a bit in the FFmpegReader, to fix some bugs. Also, being changing the cache object again, on how it cleans up pointers. Some debug code is checked in also.

Added new method to adjust the min value of a valid frame number, added a new unlimited cache option, and fixed a bug which was preventing the timeline from calling GetFrame correctly. Now timelines, clips, and readers are working together nicely.

Added an example, trying write a timeline to the FFmpegWriter. Not quite working yet though.

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!

A big refactor of the Open() method on Readers, and the constructor of Readers. All resource consuming code has been moved into the Open() methods, so the Clips and Timeline can control them better.

Added Open() to the reader base class, so all readers need to have that method now. This is to allow the timeline to better control Clips and Readers.
