Details

Right now imgFrame only has basic Lock/Unlock functionality. It then always assumes the data has been written do and will flush/markdirty accordingly. In theory we could just flush our surface once and then any read-only access would not need to bother flushing or marking dirty. This would help by not detaching snapshots needlessly saving upload bandwidth.
