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. =)

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 more audio issues, and a regression where removing the video channel (with just an audio channel remaining) caused the FPS to be incorrect.

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.

Lots of debug code with some experimental audio PTS code, to adjust for small gaps in timestamps.

Added in openMP code to improve performance on the timeline layer merging, which is very CPU intensive.

Added gravity, scale type, and percentage based X,Y location settings. All the basic transformation methods are now working. You can layer, move, fade, snap, rotate, and scale clips on the screen.

Fixed bug which froze the FFmpegReader when caching 1080p video.

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 bug in the regression in the FFmpegReader class, which prevented frame 1 from loading

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.

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 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.

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.

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.
