Note that the get_pixel_position_ll() and such functions (in the MEP9
proposal) are only for internal use by the interactive manager.  Items can
still be placed by the script wherever necessary, and if the position (in
one or multiple transformations) is necessary, one can record that in the
on_select_end callback for that artist.

In fact, one of the things that must be done in the set_position_and_size()
call (every artist will have to do this) is to set that artist's
appropriate parameters for its position and size, based on its current
transformation, that fits it within the bounding box that the user just
finished moving and dragging around.  Sorry, I know that's hard to see
without some straw-man code that I intend to post soon...I was a little
ashamed to post it in its current state ;)
