For a deeply nested display object container, bubbling
of events can be expensive. Reduce this expense by handling the
event completely in the target object, then calling the
of the event object. Calling this method prevents the event from
bubbling up. Calling this method also means that parent objects
do not receive the event.
Related gains can be realized by flattening the display object
nesting, to avoid long event chains.
Register for MouseEvent events instead of TouchEvent events when
possible. MouseEvent events use less processor overhead than TouchEvent
, when possible.
