I have a few questions about adding device support to JInput.

What is the general policy for adding new device type/support for JInput?
In particular I am adding support for space navigators and touch screens.

(Questions about native code, only deal with GNU/Linux)
(using code from CVS)


1. How often is the NativeDefinitions.java file generated?
The javadoc in the header states it is generated from /usr/include/linux/input.h.
Since the last time this file was generated, there have been some changes to the Linux evdev interface.
In particular, the ioctl() function EVIOCGUSAGE and USAGE_* constants are no longer defined. 
The ioctl() call is made from net_java_games_input_LinuxEventDevice.c.  Later, the USAGE_* constants
are checked in net.java.games.input.LinuxEventDevice.guessType().
I am using kernel version 2.6.18 (newish, but not bleeding edge)


2.  I am adding a new Controller type SPACE_NAV.  Initially it will support the 3DConnection
SpaceNavigator, though is not the only 6 DOF device on the market.  Using the JInput code
from CVS, the device is detected as a mouse.  This type of device is usually used for navigation
independent of the mouse.  So I think it deserves a separate type.


3. How do I submit my changes back to the project?


Thanks in advance,
