OnMouseUp event dispatcher.
A control calls MouseUp in response to any of mouse-up messages, decoding the message parameters into the shift-key state and position, which it passes in the
Y parameters, respectively:
Buttondetermines which mouse button was previously pressed: left, right, or middle.
Shiftindicates which shift keys--SHIFT, CTRL, ALT, and CMD (only for Mac)--were down when the pressed mouse button is released.
Yare the pixel coordinates of the mouse pointer within the client area of the control.
Override the protected MouseUp method to provide other responses when the mouse button previously pressed is released while the cursor is over the control.
