// What is CPaneCX?
// A pane is part of a complete window.
//
// There is no relation from a pane to the chrome of a full window.
// There is no frame, no document, no view, no toolbar, etc.
// No assumptions should be made, or the pane becomes non-reusable in a
// window that is yet to be invented.
//
// A pane can be put many places:
// In a dialog.
// In a navigation tool.
// In a browser.
// It is up to the place to provide the chrome. It is up to the pane to
// provide the HTML.
