If you want to take a crack at extending this test and exploring the proper return size for WTInfo and maybe also the cursor ordering that's cool.
This is pretty sad times for pressure to not work in photoshop again so I'm interested in seeing this fixed as well.
A good collection of docs on wintab is here: http://wiki.winehq.org/TabletSupport
Good example good is the windows gtk that windows gimp uses for its pressure stuff. Its linked from the wiki.
