Pushed to branch 'viranch/qtquick' in libkdegames, and corresponding port of 
kbreakout in branch 'qtquick/imageprovider' in kbreakout (note that there is a 
'viranch/qtquick' also in kbreakout which is different).

so I tried this but could not find any way to know when a resize is ending. I 
found sceneResized signal and the resizeEvent, both of which are triggered on 
all intermediate sizes.

I reliased the default value of asynchronous for QML Image is false, so I set 
it to true and the main window is no longer blocked when resizing, but the 
images become gray for fraction of second as they're rendered.
