Actually, under X11 the API for acquiring tablet information is also
quite standard, just like under Windows. Ditto for OS X (at least for
Cocoa).

The Linux Wacom drivers are a bitch to get to work (I own a Wacom
Graphire2 tablet that is sitting on my desk as I am typing this), but
once they do, apps simply have to fetch the right information from
Xinput.

Both GTK+ and Qt already have built-in tablet APIs that do the right
thing depending on the platform. Adding tablet support to SDL should
be fairly easy, seeing Qt already does it under Windows, OS X and X11.
