Called to handle the mouse event processing whenever a mouse event happens.

Parameters:

hwnd	The window handle of the window in which the user has clicked. It is one of the viewports to which an interface can be obtained from the system. To get such interface, the window handle should be passes to the functions Interface::GetViewport() as the input. Developers should call Interface::ReleaseViewport() once they are done with the viewport interface.
msg	This message describes the type of event that occurred. See Mouse Call Back Flags.
point	The point number. this is 0 for the first click, 1 for the second, etc.
flags	These flags describe the state of the mouse buttons. See Mouse Call Back Flags.
m	The 2D screen point on which that the user has clicked. Methods in the viewport interface allow this point to be converted into a world space ray or a 3D view space point. A world space ray can be intersected with the active construction plane which results in a point on the active construction plane. See Class ViewExp.

Returns:: TRUE, indicating the proc should continue to process points; or FALSE, meaning to stop processing points. If a plug-in supplied a large number of points in a command mode that uses this mouse proc, FALSE can be returned to abort the processing before all the points have been entered.
