* There are a couple of extra events that Java expects to get that don't
* actually correspond to a direct NSEvent, KEY_TYPED and MOUSE_CLICKED are
* both extra events that are sort of redundant with ordinary
* key downs and mouse ups. In this extra message, we take the original
* input event and if necessary, cons up a special follow-on event which
* we dispatch over to Java.
*
* For Java, keyDown's generate a KeyPressed (for each hardware key as it
* goes down) and then a "logical KeyTyped" event for the key event. (So
* a shift-a generates two presses, one keytyped of "A", and then two
* releases). The standard event utility function converts a key down to
* a key pressed. When appropriate, we need to cons up another event
* (KEY_TYPED) to follow a keyDown.
*
* Java expects you to send a clicked event if you got a down & up, with no
* intervening drag. So in addition to the MOUSE_RELEASED event that a
* mouseUp is translated to, we also have to cons up a MOUSE_CLICKED event
* for that case. Mike Paquette, god of Window Server event handling,
* confirmed this fact about how to determine if a mouse up event had an
* intervening drag:
* An initial mouse-down gets a click count of 1. Subsequent left or right
* mouse-downs within the space/time tolerance limits increment the click
* count. A mouse-up will have the clickCount of the last mouseDown if
* mouse is not outside the tolerance limits, but 0 otherwise. Thus, a
* down-up sequence without any intervening drag will have a click count
* of 0 in the mouse-up event. NOTE: The problem with this is that
* clickCount goes to zero after some point in time. So a long, click &
* hold without moving and then release the mouse doesn't create a
* MOUSE_CLICK event as it should. Java AWT now tracks the drag state itself.
*
* As another add-on, we also check for the status of mouse-motion events
* after a mouse-down, so we know whether to generate mouse-dragged events
* during this down sequence.
