[flexcoders] addChild vs. addRawChild and performance

[Steve Mathews]

Someone posted recently describing that addRawChild adds DisplayObject
in a way that they are not included in the size and layout of the
container (if I understood correctly). Does anyone know if this would
be better or worse for the overall performance of a Flex app? So if
you did not need layout features of the framework, would it be better
to add everything as raw children?
