SDL2 Android gesture testing app

Hi,

I’ve published a free app on the Android play store that allows one to
create a library of gestures, and to try and match against the library
of created gestures, displaying the error for a given match. Theres a
new version still being updated

https://play.google.com/store/apps/details?id=org.disinterest.gestures

The gestures seem to work great, with moderately low errors indicating
valid matches (< 40), but… simple gestures do not seem reliable. If
I make a line from left to right, and a line from right to left, then
it will reliably match the former, but often mismatch the former for
the latter. I’d be curious if anyone else has had better results?

Cheers,
Richard.
