Cocoa: Disable touch events.
Enabling touch events has a negative impact on overall
performance. In particular, enabling touch events seems
to disable scroll event compression, resulting scroll
processing lag.
Until we find a solution where we can have both proper
scrolling and touch events we choose scrolling over
touch events. Applications that disagree can enable
touch events manually:
NSView *qtView = (NSView *)QGuiApplication::platformNativeInterface()->
nativeResourceForWindow("nsview", qtWindow);
[qtView setAcceptsTouchEvents:YES];
