This package allows scrollbars to be mapped and unmapped as
needed depending on the size and content of the scrollbars scrolled
widget. The scrollbar must be managed by either pack or grid, other
geometry managers are not supported.
When managed by pack, any geometry changes made in the
scrollbars parent between the time a scrollbar is unmapped, and
when it is mapped will be lost. It is an error to destroy any of
the scrollbars siblings while the scrollbar is unmapped. When
managed by grid, if anything becomes gridded in the same row and
column the scrollbar occupied it will be replaced by the scrollbar
when remapped.
This package may be used on any scrollbar-like widget as long as
it supports the set subcommand in the same
style as scrollbar. If the set subcommand is
not used then this package will have no effect.
