    Has anybody come up with a hack to override CLIM's (as I perceive)
    mishandling of mouse clicking on valid overlapping presentations.
    The user should get a list or better yet a menu of those objects
    that those presentations represent to choose from but
    alas poor CLIM only outputs the last presentation that was placed
    on top of the others  (this should be considered a bug).  Yes, I
    know you can write yet another presentation type for handling presentation
    groups, but in my dynamic changing application display (if the user
    changes scale, etc.) that sure seems to be a lot of extra overhead
    to implement a low level capability that CLIM should handled.

The current CLIM 1.0 behavior is indeed a bug, caused by a giant bubble
in SWM's brain.  I actually fixed this in the development CLIM sources a
while ago (and have passed this fix on to ILA and Franz), but I don't
know of any effective way of getting the fix into the field.

With the fix in place, the translators for the topmost presentation are
the ones offered on the "usual" pointer button clicks, but the menu you
get when you do a right-click includes all the translators.
