This method assumes LastInput has information representing a mouse down input event. We also assume that FirstInput has a copy of the canonicalized input event. By default this just gets focus and calls IGoTool.DoMouseDown on the current Tool.

This is normally called by OnMouseDown and any other code that wishes to simulate a canonicalized mouse down event. This is not called when AllowMouse is false.
