/**
The Fl_Tabs widget is the "file card tabs"
interface that allows you to put lots and lots of buttons and
switches in a panel, as popularized by many toolkits.
\image html tabs.png
\image latex tabs.png "Fl_Tabs" width=8cm
Clicking the tab makes a child visible() by calling
show() on it, and all other children are made invisible
by calling hide() on them. Usually the children are Fl_Group widgets
containing several widgets themselves.
Each child makes a card, and its label() is printed
on the card tab, including the label font and style. The
selection color of that child is used to color the tab, while
the color of the child determines the background color of the pane.
The size of the tabs is controlled by the bounding box of the
children (there should be some space between the children and
the edge of the Fl_Tabs), and the tabs may be placed
"inverted" on the bottom - this is determined by which
gap is larger. It is easiest to lay this out in fluid, using the
fluid browser to select each child group and resize them until
the tabs look the way you want them to.
