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.
