Implement CSS-like stacking context behavior for pointer events: - Events now dispatch to views based on visual z-index order, not DOM order - Higher z-index views receive events before lower z-index siblings - Stacking contexts are properly bounded (child z-index doesn't escape parent)

I have some changes that will mostly overwrite this. I have redone the event handling and it is now significantly more robust and respects z index and also has explicit phases for capture, target and bubble. It also does hit testing using a spatial index so no more need to slowly walk the view tree for hit testing. In the changes I have, events are still dispatched in dom order, but the event context caries the visual hit path so an event handler can see/use the visual order if desired |

draft in #998. The event handling is in src/context/event.rs. needs a bit more work to make propagation work |
