Subject: [PATCH] Make camera controls more sensitive to trackpad pinch

On browsers unfortunately trackpad pinch-zoom is sent over as a wheel event. However, the magnitude of these events are decidedly smaller in practice, leading to very unsatisfying pinch zooming. Multiplying deltas by 10 when they are less than 25 in my testing is an effective fix for this.
