OnMouseMove event dispatcher.
Shift indicates which shift keys (SHIFT, CTRL, or ALT) were down when the mouse cursor is over the control.
Y are the pixel coordinates of the mouse pointer within the client area of the control.
As the mouse cursor moves across a control, this method is called repeatedly. Each time it is called, it is with the new coordinates that reflect the continuous path of the mouse cursor across the screen real estate covered by the control's visual representation.
Override the protected MouseMove method to provide other responses when the mouse cursor moves over the control.
