* A non-updating layer requiring rotation, can make use of the older rotator buffer written when the layer got first updated, rather than invoking a new rotator cycle. * A rotator play is avoided in cases where incoming layer buffer fd, offset, whf, src-rect, dst-rect, etc are similar to that of the previous input layer to the rotator. * For ex: In a usecase where video layer updates happen at 30fps and all other asynchrous UI updates happen at 60fps, instead of the traditional 60 calls of rotator play per sec, we now do only 30 thereby saving rotator bandwidth. * Property "debug.rotcache.disable" can be used to disable this feature.
