Rework internals of how VSE caching is done. Primarily to make all the caching logic more understandable from development point of view, but also has several user visible implications (more details in the PR): - Simpler and fewer caching UI options, - Disk cache is gone (primary reason: proxies are kinda the same thing), - VSE cache size set in preferences is actual size used for VSE caches now (previously caching stopped as soon as whole Blender used that much memory, even if some memory usage was not about VSE at all), - Certain scenarios of cache invalidation are faster now.

|
|
* Cached intermediate images used while rendering one sequencer frame.
|
|
* - For each strip, "preprocessed" (strip source, possibly
|
|
* transformed, with modifiers applied) and "composite" (result of
|
|
* blending this strip with image underneath) images are cached.
|
|
* - Whenever going to a different frame, the cached content of previous
|
|
* frame is cleared.
|
|
* - Primary reason for having this cache at all, is when the whole frame
|
|
* is a complex stack of things, and you want to tweak settings of one
|
|
* of the involved strips. You don't want to be re-calculating all the
|
|
* strips that are "below" your tweaked strip, for better interactivity.
