   I don't understand the double click prohibition. Seeing as how the
   mouse barely moves during a double click, how is that less precise
   than a single click? Anyway, if you are one pixel off, you can
   still move the thing. If double click is out of the question, then
   have control- click define the center point.

Think about the mechanical action required for a double click: you
have to hold the mouse very carefully while clicking it twice in rapid
succession.  It would be very easy to move it by several pixels while
you're doing it.
