Features a lot of timeline-related cache optimizations as well as general
optimizations and improvements in timeline behavior. Should improve
usability significantly.
- Replaces QLinkedList with std::list as recommended by Qt docs.
- Replaces QWheelEvent::delta() with QWheelEvent::angleDelta(). This
should also benefit trackpad behavior.
Old code (imported from elsewhere) has been cleaned up significantly, made more
understandable/maintainable, and conformed to the rest of the code style.
As opposed to simply leaving all values in the table, nodes can now "take"
values that they use to free up memory (e.g. "taking" input buffers if they're
used to produce an output buffer).
This is a fairly large change, expect regressions.
A pool can allocate/destroy any amount of arenas during runtime, meaning it
won't run out of memory but we still get the advantages of one large allocation
as opposed to hundreds of small allocations.
Implemented the ability to copy/paste blocks/clips in the timeline. This did
require some large scale changes and reworking of the copy/paste system
introduced a few commits ago, but should be largely functional now.
Should address any XML parsing issues and allows for simpler, more maintainable
code. Should also address a crash that could occur when pasting nodes that had
inputs that weren't copied.

Indexing is a lengthy process and had a high chance of getting RenderWorkers
stuck doing it rather than being responsive to cache requests. This commit
introduces a system where workers never index media, but instead signal that
media is not ready to their RenderBackends which ensure that the media gets
indexed and re-queues the affected frames when those indexes are ready.
When adjusting a slider, keyframe time, or curve value, it is undesirable to
re-cache the entire affected area while the user is still dragging UI objects.
Since the video is unlikely to be playing, the priority must go to the
currently active frame so the user gets visual feedback on the rendered image
as soon as possible. This was implemented in some areas, but this commit should
have that functionality in all areas.
`rational` is supposed to "fix signs" and "reduce" whenever its values are set,
but I neglected to do this when its values were set by an AVRational. Now it
will do so on both.
