/Much/ better, thanks a lot :)

I fixed the thing in the Acecad driver too now, and now drawing in
Inkscape follows the cursor position, which is a very nice thing.

I'm left with another issue, but I'm not sure it's related: when using
the calligraphic pen in Inkscape I get a very 'blotched' line, as if
'full-pressure' blobs were inserted along the way. I'm not sure wether
this is an Inkscape or driver bug though. It sort of looks like a lot
of 'button 0' events are inserted along the way. And I can't test what
happens with xinput because for some odd reason xinput list <device>
is the only thing that works (xinput test or anything else claims they
can't find the device).

I have no idea if there is anyone using my driver on XFree86, so I
just check the version against 1.4.0 ... maybe it's not the wisest
thing but it works :P
