Detailed Description

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.
