Description
The mouse event data structure, MAV_mouseEvent, is passed to
the application supplied callback function (set with
the mav_callbackMouseSet function) upon mouse button events and details
that event.
-  win
window in which event occurred.
 
-  x, y
position of mouse relative to window origin when event occured.
 
-  root_x, root_y
as (x,y) but relative to root window.
 
-  line
the line from the eye point through the world position of the mouse when
the mouse event occured.
 
-  intersects
MAV_TRUE if line intersects an object, MAV_FALSE otherwise.
 
-  obj
the object intersected by the line (if any).
 
-  objint
the details of any object intersection.
 
-  button
MAV_LEFT_BUTTON, MAV_MIDDLE_BUTTON or MAV_RIGHT_BUTTON, to indicate
which button generated the event.
 
-  movement
MAV_PRESSED if button down event, MAV_RELEASED otherwise.
 
See MAV_keyboardEvent for why obj will not necessarily be the same
as the MAV_object passed to the event callback function.
