Round up when generating the scaledSize.
Round using rint instead of always rounding up. Cast width, height to local size_t variables to avoid issues with creating a new CGBitmapContext with the given width/height. Rename bufferSize ivar to cachedBufferSize.
Call -startLiveBlurringIfReady when moving to a new superview to trigger -forceRefresh, if necessary.
Switched back to rint, but only use it for creating the Bitmap Contexts; make sure that width + height aren't 0 when bufferSize indicates the backing view isn't "empty".
