Initial Comment:
moving an object after setting 'set picking DRAW' does not send a message to the MessageCallback function

Message:
Ah, I see. The documentation is referring to the SHOW DRAW command, which
one could execute later. I agree that it would be nice to have this, and I
think it could be handled with a callback. But no such callback exists. We
do have the moveAtomCallback, so it does might make sense to have
moveObjectCallback or something like that. Feature request!

Message:
The documentation talks about a message callback:

 set picking DRAW
The vertices of all draw objects are highlighted. Holding the SHIFT key
down while dragging moves the object to a new location ("shifts" the
object); holding ALT down while dragging moves a single vertex to a new
location ("alters" the shape of the object). The draw command required to
reproduce the object can be seen immediately using the Java console. This
new command can also be seen via message callback, or in the Jmol console
using show DRAW.

currently you can use 'show DRAW' but if you want keep track of what a user
does - e.g. moving some plane around - to update a web gui, I find a
callback more reliable, with 'show DRAW' you need to create a loop that
issues that command and then you only get the last change draw object.

Message:
no message for set picking dragatom, either. Why do you expect one?
