If your object is the type of thing IDLgrView knows
what to do with (I.e, models, graphics atoms, etc.),
then IDLgrView will know what to do with it. Specifically,
it will need a DRAW method to implement the graphics
rendering. (Models, of course, *have* a draw method, so
if your new object is subclassed from a IDLgrModel object,
and I'm sure it will be, then the DRAW method is already there.)

Be sure you write the DRAW method if you are creating new
graphics objects, or add your graphics objects to a model
(I.e, subclass your object from an IDLgrModel), and you
are good to go. See something like HCOLORBAR__DEFINE for
an example:
