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.

Added the ability to specify the image type and scale of any frame when calling the Save() method on a frame. This makes it easy to save any frame as any image type at any size image... very useful indeed.

Fixed the audio resampling by adding a new class called AudioResampler, which maintains state between calls to the JUCE resampler. Maintaining state allows JUCE to remove the discontinuities between the frames, and removes all the pops and crackles.
...
This is a major commit, and changes many things, including build scripts, new classes, and how the encoder works.

Added in JUCE audio resampling, and have lots of resampling debug code still in place.

Added some new methods to access audio data: channels, samples, etc... Also, added initial unit tests for the FFmpegReader class, including waveform checking against an actual audio file.

Refactored FFmpegReader code a bit, fixed many, many memory leaks, and many valgrind errors. Now the memory seems very stable, and the seeking and stream walking seems very solid.

1) Successfully got OpenMP working with the video processing method.
...
2) Added new "processing" flag, to help determine if a frame is being worked on in a thread
3) Added a new cache Display() method, for debugging reasons

Got ffmpeg and juce compiling and mostly everything working again. FFmpeg is the newest version, and so is JUCE.

Fixed tons of issues related to video timebase being different than the video framerate. Also, added new properties for interlaced video, correctly detect pixel ratio, and fixed Display() to adjust for pixel ratio. Also added sample_rate to a frame, so it can playback audio at the correct rate. Refactored FFmpegReader to make most methods private, and only expose the important methods publicly.

Added a DisplayWaveform method on a frame, to help debug audio issues. It uses ImageMagick to draw each channel and all samples in each channel.

Some major refactoing of the FFmpegReader, to allow for audio and video packets that are out of order.
