Would it be possible to discuss this on IRC?

The viewport meta handling depends on the device and UI:

- device height/width
- device DPI
- actual viewport given the UI (if you consider the iPhone, this is the size when all ui components are shown, incl. the address bar) something that changes given orientation.

The UI also is responsible for doing rotation animation, and adding the components, thus affecting the actual viewport.

All even handling such as panning, pinch zoom etc are handled by the UI, so the UI needs to enforce the limits. It is true that could could handle some of this in WebKit itself, but for instance with tiling (which allows non-blocking scrolling) we need to handle this on the UI.

We could make special views in WebKit2 that handles this behind the scenes and thus removes the public C API, but that is not really a possibility for Qt, as Qt and QtWebKit lays below the UI toolkit, in our toolchain.
