/* Misc3DMouseDriver.h
*
* The MouseDriver is the a basic 3DMouse dirver class. It provide some simple
* methods to handle the event composition and sending.
*
* Usage: Create a subclass and use the deliver... methods. But be careful!
* We assume that all the values we get in our deliver method are from
* a rightHanded device. Please ensure that they match this orientation!
*
* Notes: setTarget takes care that only object that conform to the
* Misc3DMouseTarget protocol will really become a target.
*
* In the none existing case that a target might decide to switch its
* world handedness from left to right handed (or visa-versa) it HAS TO
* set the mouses target again. There is no other way to set the
* handedness.

// Targets of a 3DMouse have to implement the following protocol.
// This will allow the driver to adjust the events to fit the programms
// needs.
// The transformationWill-Did stuff will not be handled automatically by the
// basic Mousedriver. It is not easy do fnd the right point when to send those
// messages. Ever mouse river has to do that on his own!
// Those messages are ment to allow the target to switch to a faster display
// style for the manipulations. It is not wise to wrap every single event that
// way. You should wrap 'transformation sessions'.

* History: 11.04.94 Should simplify the other mouse drivers.

*
* Bugs: - Yes. deliverKeys does nothing right now. It should check the sting
* and ensure that the ASCII codes are sorted lowest first.
