Put them in their own IDLgrView object, and set that view's
location, dimension and viewplane rectangle properties so that it
matches the plotting area in both device and real-world coordinates.
Then put the axes, annotations, etc in a second, larger view object
which encloses and overlays the first. Put both views into an
IDLgrScene in the order given above so that annotations overlay the
plot and not vice versa, and set the second view to be transparent so
that it doesn't erase the first.
