ffmpeg's libswscale is used to do RGB<->YUV conversions on movie reading and writing. The "context" for the scale operation was being created and destroyed for each movie clip / animation. Now, maintain a cache of the scale contexts instead. E.g. in Gold edit, it only ever needs two contexts (one for reading source movie clips since they are all exactly the same resolution and format; and one for rendering the resulting movie). During playback, on some of the "slow" frames (camera cuts) this saves 10-20ms (Windows, Ryzen 5950X). Rendering whole movie goes from 390sec to 376sec.
