getPositionIsSizer() returns the index of the item in a 1D sizer, or
the (row,col) tuple of an item in a 2D sizer. It doesn't return the pixel
position.
There are a lot of choices for determining an object's location,
relative to many reference points:
formCoordinates(): relative to the object's form
containerCoordinates(): relative to the object's container
objectCoordinates(): relative to an object
absoluteCoordinates(): relative to the screen
relativeCoordinates(): screen coords. relative to object
Look through the docstrings for these methods in dPemMixin.py for
explanations as to how each of these is used.
