There isn't one we can acceptably use on X, and the other platforms
(such as GTK and NS) offer very different meanings of what constitutes a
"gesture" which are difficult to abstract around in a useful manner.

Other cross-platform programs I examined such as Mozilla Firefox also
implement gesture recognition from scratch.

Thanks.
