OptionsCanvas

Window that is designed to be like a form for options.  The window is sized to
be tall enough to hold all options, so it needs to be inside another window that
scrolls.  Note that this uses a dialog box in order to get the standard dialog
box backround painting and keyboard navigation.  The dialog resource is
completely empty.
