* don't crash when parent=0 is passed in * don't divid by 0 when we have no children * have the (fugly) setManagingLayout and unsetManagingLayout and managingLayout methods * do some memory management so layouts that are thrown around don't get lost in the heap some unit tests would be nice. hell, a design document on the layout stuff would be nice. i know we're only keeping this around for 4.0, but ... yeah. ugh.
