I just noticed that GridBagLayout has some methods (not constructors)
that begin with a capital letter:

- AdjustForGravity()
- ArrangeGrid()
- DumpConstraints()
- DumpLayoutInfo()
- GetLayoutInfo()
- GetMinSize()

This is contrary to our code conventions (not to mention our API
conventions),and thus is confusing. (One expects different
capitalization to indicate some different meaning.) In the next
release, we should cover these with correctly capitalized methods
and either not document these versions or say that they're for
backwards compatibility only.
