Title: Improve on pinch-to-zoom support

Along with some minor cleanup, this solves two significant problems with
pinch-to-zoom:

1. Pinching only worked on the image area, not the whole screen, making
it difficult to start the gesture. The second commit fixes this, without
changing the flickable anchoring.

2. The entire image jittered around when zooming, because some flickable
values were being updated before PinchArea had applied scale changes.
Changed this to use bindings, so everything updates in the same frame,
and doesn't jitter.
