Yes, that's right.. the SGI program I wrote.
The code is still there on my personal home page:
http://seriss.com/people/erco/wacom/
One of the few pure xlib/motif/opengl programs I ever
had to write.. I hope it stays that way..!

I guess the trick was to figure out where in FLTK's
X11 code to merge that stuff in.
I think the wacom related stuff is all the calls
that (a) walk the device list to find the wacom tablet:
XListInputDevices()
XOpenDevice()
XFreeDeviceList()
..and (b) register motion events:
DeviceMotionNotify()
XSelectExtensionEvent()
..and then (c) in the FLTK code there's probably a big
'switch' statement that can find if the event.type ==
wacom_valuator_event_type
..and read in all the wacom data into an array that our own FLTK methods
can access.
Or something to that effect?
