/**
* The four-way splitter is a layout manager which manages
* four children like four panes in a window.
* You can use a four-way splitter for example in a CAD program
* where you may want to maintain three orthographic views, and
* one oblique view of a model.
* The four-way splitter allows interactive repartitioning of the
* panes by means of moving the central splitter bars.
* When the four-way splitter is itself resized, each child is
* proportionally resized, maintaining the same split-percentage.
* The four-way splitter widget sends a SEL_CHANGED to its target
* during the resizing of the panes; at the end of the resize interaction,
* it sends a SEL_COMMAND to signify that the resize operation is complete.
