and DoLayout(). When the B_SUPPORTS_LAYOUT view flag is set (as is by
default when using one of the new constructors) the BBox completely manages
one true child (the first child that is not the label view).
* Centralized the layout related computation in new method
_ValidateLayoutData(). The computed infos are cached in a new private
LayoutData structure.
* GetPreferredSize() was broken in several respects. It does now return the
same result as PreferredSize(). If B_SUPPORTS_LAYOUT is not set, these are
the sums of the insets induces by the frame and the label. I.e. those values
can for instance be added to the child's preferred size to compute the
preferred size of the compound.
Not sure, if the Haiku-only TopBorderOffset() and InnerFrame() functions still
make sense. With layout management they're actually superfluous.
