The 1.0 Form does not calculate its initial size correctly in many
cases (the most common being child attachments to the bottom or right
edge of the Form).

The allowOverlap resource is an artifact of the class heirarchy of the
Form--it comes from BulletinBoard--and is ignored.  This is true in 1.1
also.  There is some chance that this resource will be honored at some
time in the future.

There is no simple answer.  The "standard" answer is to set up a map
callback and in that callback query all of the children for their size,
do the necessary calculations and size the form accordingly.

Good Luck!
