Routine Description:

    Called when there are mouse packets to report to the RIT.  You can do 
    anything you like to the packets.  For instance:
    
    o Drop a packet altogether
    o Mutate the contents of a packet 
    o Insert packets into the stream 
                    
Arguments:

    DeviceObject - Context passed during the connect IOCTL
    
    InputDataStart - First packet to be reported
    
    InputDataEnd - One past the last packet to be reported.  Total number of
                   packets is equal to InputDataEnd - InputDataStart
    
    InputDataConsumed - Set to the total number of packets consumed by the RIT
                        (via the function pointer we replaced in the connect
                        IOCTL)

Return Value:

    Status is returned.
