class IUP_CBOX
-- Container for position elements in absolute coordinates. It is a 
-- concrete layout container.
-- The IupCbox is equivalent of a IUP_VBOX or IUP_HBOX where all the 
-- children have the FLOATING attribute set to YES, but children must use 
-- CX and CY attributes instead of the POSITION attribute.
