Stylus tilt, which I get with event_x_tilt() and event_y_tilt() need some corrections:
1. On Windows, Y tilt value is inversed comparatively to Linux implementation.
2. On Linux, with LinuxWacom drivers version 0.7.2 - 0.7.6, tilt values are incorrect.

I have a small patch which fixes this, and also improves tablet support with new TABLET event, which allows to retrieve tablet's native position (so you can use high-resolution input from modern tablets).

The patch is for both Linux and Windows, and I've added stubs for Mac OS X, as we don't have tablet support there.

See my posts at fltk.development for details:

+ I post here a small program for tablet testing for FLTK2, which looks like this: http://www.highcat.by.ru/heap/ttest.jpg

I've updated the patch:

added support for relative positioning inside widget in tablet's coordinates. Updated demo program; - see screenshot: http://www.highcat.by.ru/heap/ttest.jpg
