These are the ones you want.

This is done by default if the mouse mode IDs are set.

OK, good.

It doesn't matter that the layer is a MapMouseInterpreter, you don't
want it to be. The interpreter is the MapMouseListener.

You won't get a mouseClicked() call. Using the MapMouseInterpreter
moves things up a level.

You probably won't, if your list is empty. Look at the last part of
the referenced message about receivesMapEvents() for more raw events.
Of course, if you want to receive the mouseClicked(), mouseMoved() etc
calls directly, have your layer extend MapMouseListener and return the
"Gestures" string in getMouseModeServiceList(). But if you are just
going to be going over OMGraphics with those events, the interpreter
does that work for you.
