I would love to hear where you get this information from, because the one
thing we're suffering from is not knowing how our users use the tablet.
Relative mode is common (and default) in the wacom driver for the lens/puck
tool but few users have that one. Relative mode for the stylus is available,
but we have little to no data on who's using it.

So, please tell me how you know this, because we desparately need this type
of information and I want to figure out more usage data.

That aside, relative mode is handled by the compositor, it's not something
exposed on the protocol. A client always gets absolute coordinates,
regardless of the input mode.

Please suggest a rewording that makes this clearer.

Cheers,
