Checks whether a mouse event was generated by the pen driver.
BOOL IsPenEvent( UINT message, LONG lExtraInfo )
Windows mouse message being queried.
Value returned by GetMessageExtraInfo
for the given message.
Returns TRUE if the mouse event referenced by the message
parameter was generated by the pen driver; otherwise, returns FALSE.
Mouse drivers that have not been updated to be compatible with pens may
produce an event that cannot be distinguished from a real pen event. This has a very
low probability of occurring.
