+/**
+ The Fl_Tile class lets you resize the children by dragging
+ the border between them:
+
+ <P ALIGN=CENTER>\image html Fl_Tile.png </P>
+ \image latex Fl_Tile.png "Fl_Tile" width=4cm
+
+ <P>For the tiling to work correctly, the children of an
+ Fl_Tile must cover the entire area of the widget, but not
+ overlap. This means that all children must touch each
+ other at their edges, and no gaps can't be left inside the
+ Fl_Tile.
+
+ <P>Fl_Tile does not normailly draw any graphics of its own.
+ The "borders" which can be seen in the snapshot above
+ are actually part of the children. Their boxtypes have been set
+ to FL_DOWN_BOX creating the impression of
+ "ridges" where the boxes touch. What you see are
+ actually two adjacent FL_DOWN_BOX's drawn next to each
+ other. All neighboring widgets share the same edge - the widget's
+ thick borders make it appear as though the widgets aren't actually
+ touching, but they are. If the edges of adjacent widgets do not
+ touch, then it will be impossible to drag the corresponding
+ edges.</P>
+
+ <P>Fl_Tile allows objects to be resized to zero dimensions.
+ To prevent this you can use the resizable() to limit where
+ corners can be dragged to.</P>
+
+ <P>Even though objects can be resized to zero sizes, they must
+ initially have non-zero sizes so the Fl_Tile can figure out
+ their layout. If desired, call position() after creating the
+ children but before displaying the window to set the borders where you
+ want.
+
+ <P>Note on resizable(Fl_Widget &w) :
+ The "resizable" child widget (which should be invisible) limits where the
+ border can be dragged to. If you don't set it, it will be possible to
+ drag the borders right to the edge, and thus resize objects on the edge
+ to zero width or height. The resizable() widget is not
+ resized by dragging any borders. See also void Fl_Group::resizable(Fl_Widget &w)
