What is the best way to add new item types to XView 2.0's
Panel package ???

Currently I am making some display only items (decorations) such
as lines, boxes, circles, etc.  I have been simply making a 
PANEL_MESSAGE type item with no message and XV_SHOW FALSE, then
adding my own attributes with XV_KEY_DATA. Then when the panel
receives a repaint call I cycle through all the items in the panel and
handle the redraw for the new item types i have defined.

I noticed a Panel item type "PANEL_EXTENSION_ITEM" in panel.h
but have had no luck trying to use it.

Thanks,

Stuart
