Detailed Description

KisFrameCacheSwapper is the most highlevel facade of the frame swapping infrastructure. The main responsibilities of the class:

1) Asynchronously predict and prefetch the pending frames from disk and maintain a short in-memory cache of these frames (already converted into KisOpenGLUpdateInfo)

2) Pass all the other requests to the lower-level API, like KisFrameCacheStore
