[Qt-qml] Qml WebView performance issues -- how to address?

[Ivan De Marino]

I use N900 (no overclock), without OpenGL rendering.
I get myself not as good performances as on the desktop.

And, more important, the performances of QDeclarativeWebView are inferior to
QWebView.

What would be REALLY nice is that the rendering was done in a way that would
allow panning around while loading. The slowly-ness would be much less
perceived (like on iPhone).
