Thanks, this is working now.  However, xournal is still won't accept any
input (unless patched) because it discards events due to device_state
not being set correctly.

Thanks, this is mostly working now.  There are still instances where
proximity events lead to a crash, see the attached gdb session.

It seems like XIGrabButton doesn't accept XIAnyModifier.  Also, the
example code in xinput uses an older incompatible interface (patch
If XIGrabButton is called on a SD, the SD is not detached when the grab
is activated.

Okay, fair enough, this is not really important anyway.
