** Description changed: - The example program 'grip-test' does not appear to respond to input from - any touch device. + [Impact] - Tested with a Synaptics PS?2 touchpad, an Apple Magic Trackpad, and a - Dell XT2 (nTrig) touchscreen. + * The library was not supplying and gestures to client callers because + of underlying change in the underlying gesture recognizer conflicting + with an incorrect assumption in the libgrip library design. The + assumption was that touch input device IDs were persistent across + gesture recognizer instances, which has never been guaranteed to be + true. + + * This bug renders the entire libgrip functionally useless. + + * The bug fix moves to the latest version of the GEIS interface so + obviates dependency on incorrect behaviour in the previous + implementation. + + [Test Case] + + * Using a touchscreen, invoke the eog photo viewer program and attempt + to zoom a photo using the pinch gesture. Without this patch, there will + be no response, with the patch the photo should zoom. See also + #1120149. + + [Regression Potential] + + * A programming error in the library could result in crashes in the eog + or evince applications.
