[comp.windows.x] Input devices for X

Help! I'm considering how an X server should behave when given, instead of the 
garden varity mouse, a data tablet. A few issues come to mind:

- are physical x,y data tablet points meant to be forced into the server
	in order to place the cursor EXACTLY where the tablet says, or
	does the pointer start out in mid screen, and move with the same
	acceleration behavior as a mouse?
- what good is a tablet :) if the behavior is just like a mouse?
- if the data tablet should be treated literally, meaning locate the cursor 
	exactly as represented by the tablet, what does acceleration, etc,
	mean? Nothing? How can a client effect those - it can't.
- a client warps the pointer; does it warp right back to the physical absolute
	location specified by the tablet crosshairs, or not?  If the tablet
	is only a translation device, I guess not. If the tablet is being used 
	to map absolute points (maybe a client is digitizing data) then the 
	pointer must bounce-back? ugh.
- do I need a little hand which reaches out to move the tablet puck to where the
	cursor was warped? :)
