* The most important fix is that in BMenuField::_ValidateLayoutData(),
divider was calculated, but then never used. If the menu field was not
using the layout management, it should take the existing fDivider into
account, but never did. This caused #2728.
* Added some tracing that helped me debug this.
* Fixed a bunch of layouting inconsistencies. It will also improve some
unnecessary resizing of the menu bar.
Will test all of this some more. But in the test app I do have, the BMenuField
works more like in BeOS now.
