Mouse events
The following mouse events are available when the mouse is moved over the video window:
OnMouseDown : TOnVideoMouseUpDown
OnMouseMove : TOnVideoMouseMove
OnMouseUp : TOnVideoMouseUpDown
(activated only if MouseWheelEventEnabled is set to true)
If TranslateMouseCoordinates is enabled (default), the mouse events return the real corresponding x, y positions on the video source, even if the video window is stretched.
