Refactoring timeline_frame_number out of apply_layer() and TimelineInfoStruct, we already have this data in scope (on the background frame instance)

Refactor of global timeline effects, to address a regression with global/timeline Mask/Transitions no longer working correctly. This was caused by an optimization that broke the general behavior of the global transitions.

Removing caching from Clip object. Causes too many issues and does not add any performance (in my tests)

Large refactor of OpenMP integration (or rather the removal of OpenMP on the Timeline and FFmpeg-related classes). The logic behind this decision, was based on profiling libopenshot and the amount of wasted CPU idle time on all the various threads. The slow code is still synchronous, and all the threads must wait on each other, adding additional overhead. So, removing lots of unneeded threads, and simplifying the underlying Timeline->Clip->FFmpegReader flow. Also, removed 2 calls to QPainter::drawImage, by improving the flexibility of Clip->GetFrame.

Reducing the # of threads on the Timeline in half, with a minimum of 4. Trying to experiment and reduce stuttering.

Improving performance after working with google-prof, to profile CPU. Calling OMP_MP_NUM_PROCESSORS less often, since it's quite expensive according to profiling. Adjusting Timeline final_cache to match the video caching thread max_frames, so one doesn't clobber the other. Also, fixing an issue with openshot-player, where a video file with no audio skips horribly.

Reverting 'clear the cache when the user seeks' experiment. It was a failed experiement, not to mention that it destroys performance on the "Transform" tool.

Improvement to video caching thread, to recover from the separation of cache vs display frame #. Also found a mutex that was needed, to prevent crashing when the video thread calls timeline::GetFrame at certain times... colliding with another thread (and independent of OpenMP).

Large refactor of Timeline, TimelineBase, ClipBase, and Clip, to allow a Clip access to the parent timeline instance (if available), and thus, certain properties (preview size, timeline FPS, etc...). This allows for a simpler rendering of Clip keyframes (during the Clip::GetFrame method), and a simpler Timeline class, that can change the preview window size dynamically and no longer requires a Singleton Settings class.
...
- Also removed "crop" from Clip class, as it was never implmeneted correctly, and we have a fully functional "crop" effect when needed
- Added caching to Clip class, to optimize previewing of cached frames (much faster than previous)

Fixed a bug with cropping logic on Clip (disabled it temporarily). I need to replace the Crop functionality with a more robust cropping tool. Also, updated Timeline to use the MaxWidth/MaxHeight settings when calling the clip (since those are set when the screen is resized).

Refactored the Settings::Instance()->MAX_WIDTH and Settings::Instance()->MAX_HEIGHT out of the Cilp class. GetFrame() now has an overload which specifies the width, height, and samples needed. Otherwise, it returns the Clip image based on the source reader (width, height, num samples).
