If your application is a layer, then it will received the projection
from the MapBean when it is added to it. To get MouseEvents from the
MapBean, your layer needs to listen to the MouseMode that is active, or
be a MouseListener to the MapBean directly.

If you want to defined graphics that are geographically based, then you
probably should create OMGraphics for the shapes and images.

Sure - the OpenMap projections are just objects, and they can be used
outside of an OpenMap application.

It all depends on what you want to do. If you want to create
OMGraphics, then it might be easier to work within the OpenMap framework
and modify the EditableOMGraphics to get the application feel you want.
