Pivot does not make a distinction between single clicks and double clicks. A
click of count 1 will always precede a click with count 2 and so on. As I
recall, this is similar to how mouse events are handled in AWT/Swing.
Handling it any other way would require the platform to wait for some period of
time after a single click has occurred to make sure that the user isn't going
to click again, which could introduce some subtle (and quite possibly annoying)
usability issues.
