Hi Bernhard,

I see your patch significantly affects the performance, but I need to
know one thing before I apply it. Does panning work fine with other
input devices (i.e. ones that do not send events with high frequency)?
If so, then maybe we should have a second look at the
wx_view_controls.cpp #ifdef instead.

Regards,
Orson

Cocoa events have a hasPreciseScrollingDeltas method that will provide this information.  It is used in wxWidgets window.mm, for instance, when translating NSEvents to wx events.
