It seems to me that having colorbars and legends attached to
"targets" is a good idea in theory (as long as you don't
think about it too long), but is a disaster in practice,
for exactly the reasons you see here. They are not flexible
enough to be used in all the myriad ways people use them.
They would be much more useful if they could be detached
from targets and treated like any other graphical unit to
be added to a window. (And, it would be *extremely*
helpful if they would stay put when the window is resized!)

Cheers,

David
