These kinds of generic WTF includes should probably be included without an #if. Having a precise include set for each combination doesn’t seem helpful.

final?

NSEvent * formatting inconsistent here.

int, not double?

> Source/WebKit2/Shared/mac/WebGestureEvent.h:70
> +    float m_gestureScale;

float, not double?

> +    RefPtr<EventDispatcher> eventDispatcher(this);

I normally like "= this" instead of "(this)"; not sure why. I guess that "()" is my initialization syntax of last resort. I even prefer the "{}" since it’s pickier about types and less likely to look like a function declaration.

No need for the blank line. It’s not like local variables need to be separated at the top. Reads better without it.

Matches all the other events.

Matches WebTouchEvent.
