On Qt5, using pinch will inevitably cause tilt. It's annoying, so it is disabled by default.
In the future, it's best to introduce some kind of threshold to overcome for the tilt to be triggered.
Fixed a bug where starting tilting with LMB+RMB with LMB in sketcher
caused odd behavior.
No more messagebox upon hitting H key when the cursor is over nothing
(replaced with a warning). The messagebox was very annoying when trying
to hunt a point with touch input.
Navigation by gestures didn't work after double-clicking a constraint in
sketcher to edit a value. This was probably caused by the last mouse
button release event not reaching the viewer.
