* Update derived data before operations.

* Precomputing this data speeds up later rendering, because some items
* can be omitted.
*
* Currently this method handles updating the visual and geometric bounding boxes
* in pixels, storing the total transformation from item space to the screen
* and cache invalidation.
*
* @param area Area to which the update should be restricted. Only takes effect
* if the bounding box is known.
* @param ctx A structure to store cascading state.
* @param flags Which internal data should be recomputed. This can be any combination
* of StateFlags.
* @param reset State fields that should be reset before processing them. This is
* a means to force a recomputation of internal data even if the item
* considers it up to date. Mainly for internal use, such as
* propagating bounding box recomputation to children when the item's
* transform changes.
