* The Switcher layout manager automatically arranges its child
* windows such that one of them is placed on top; all other
* child windows are hidden.
* Switcher provides a convenient method to conserve screen
* real-estate by arranging several GUI panels to appear in the
* same space, depending on context.
* Switcher ignores all layout hints from its children:- all
* children are stretched according to the switcher layout
* managers own size.
* When the SWITCHER_HCOLLAPSE or SWITCHER_VCOLLAPSE options
* are used, Switcher's default size is based on the width or
* height of the current child, instead of the maximum width
* or height of all of the children.
