Subject: [PATCH] latin: 5-point tactile alphabet

Proposal by Tmeister on http://www.incatena.org/viewtopic.php?f=4&t=41001
built for blind reading and writing similar to braille but allowing
one-handed input.

Original hexagon dots are barely distinguishable at this size, so prefer
circles for simplicity and similarity with braille.
