The caller needs to know where exactly a logo picture is located
inside VLC video output window. Therefor the mouse coordinates in VLC
video output should be obtained and returned to the event listener
which happen to be a JS callback function. The position of the mouse
against the desktop or browser window is irrelevant for this usage.

Instead of providing this generic mouse event solution it is possible
to export a 'logo-object-moved' event (and possible do that for all
video filters that support moving their object in the video output
area).
