r=me with some itches.

Would be neat with a comment here explaining that the ultimate plan is to only initiate the gesture upon TouchBegin.

> Source/WebKit2/UIProcess/qt/QtPinchGestureRecognizer.h:42
> +const qreal pinchInitialTriggerDistanceThreshold = 5.;

Why not put this in the cpp file?

> Source/WebKit2/UIProcess/qt/TouchViewInterface.cpp:34
> +    , m_pinchStartScale(1.f)

Coding style, unnecessary .f suffix.

> Source/WebKit2/UIProcess/qt/TouchViewInterface.cpp:69
> +void TouchViewInterface::pinchGestureRequestScale(const QPointF& pinchCenterInPageViewCoordinate, qreal totalScaleFactor)

The name of this function is a bit weird. setScaleFromPinchGesture() perhaps?

> Source/WebKit2/UIProcess/qt/TouchViewInterface.h:44
> +    void pinchGestureStarted();
> +    void pinchGestureRequestScale(const QPointF&, qreal);
> +    void pinchGestureEnded();

I would have used did* style naming for these.
