Updated keyframe system to only process them if they change, to improve performance.

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.

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.

Added a new DummyReader, which can be given any framerate, samplerate, width, height, etc... and used in unit tests, such as the FrameMap unit tests.

Refactor of FrameMapper, and added in audio sample remapping..

Started working on the FrameMapper, to correctly map audio samples to the target framerate.

Removed some unneeded methods, due to the previous refactor involving shared_ptr objects. They no longer require some special overloads which "delete" the objects in the cache.

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.

Fixed a regression with disabling seek on the FFmpegReader. It runs slower than seeking, but has no artifacts of seeking, and is frame accurate.

Fixed the seeking and cache code to work correctly. Also fixed a huge memory leak with the new AVPicture structs. Now the time mapping works both directions, and with no major memory leaks!

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.

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 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!

Improved Timeline sort code to use both Position() and Layer().

Added a FrameRate() method to the timeline, to get or set the fps. Also, added a unit test for that, and refactored some header files to be alphabetical.

Added some functionality to the timeline GetFrame() method, and build a way to update the list of opened clips, to manage which files are open and closed, etc...

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.

Protected the Open() and Close() methods better, so the FFmpegReader will not crash. Also, made the Open() method public, so the Timeline and Clip classes can control the reader better.

Overloaded Clip comparison operators, to use the Position() of clips for sorthing routines. Also, added the AddClip method, to add clips to a timeline (and sort them by position).
