+Subject: lib: Add accessor for minutia coordinates
+
+Add fp_minutia_get_coords() so that debugging applications can show the
+detected minutiae along with the captured image.
+
+This will also help fix the positively ancient fprint_demo.
+
+See https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=907470
