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 more audio sample issues with time mapping

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.

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.

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..

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.

Fixed a regression with the FFmpegReader, to always get frame 1 first, to calucate the PTS offsets, etc... Also, fixed a bug on the timeline, and now i'm 1 step closer to having it all work. =)

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!

Implemented the Close() method, so it closes all clips' readers on the timeline

Refactored constructor() methods on readers again, to call Open() and then Close() methods automatically, to populate the info struct. And moved the GetFrame() call out of the Open() method, because it was unneeded and slowed down the Open() method.

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...
