Not that I know. I'm not a Google Maps expert though.


Some explanations:

Pinch zooming scales the “layer container" div. This div contains the
layers that OpenLayers itself is responsible for moving. Google layers are
moved by the Google Maps API, so they're not in the layer container div.

There may be ways to have the Google layer be scaled while pinching, but I
personally don't know how to achieve that.
