abstract class for wrappers of geometric objects.
These allows any geometric thingy to be used as a component in a view.
(background info: geometrics are mathematical objects - they do not
keep any color or lineStyle attributes. Wrappers add this information
and can also be used as components of a view)
Notice:
this class was implemented using protocol information
from alpha testers, from reading PD programs and
from the Hopkins/Horan book.
- it may not be complete or compatible to the corresponding ST-80 class.
If you encounter any incompatibilities, please forward a note
describing the incompatibility verbal (i.e. no code) to the ST/X team.
