<pre>So, in ThreadedCoordinatedLayerTreeHost we have:
- sizeDidChange: called when the main frame contents size changes, but that changes also the coordinator size
- viewportSizeChanged: called when the viewport size changes, but doesn't change the coordinator size
this is very confusing not only because we are mixing both sizes, but also because sizeDidChange is used in all other layer tree host implementations as the viewport size.</pre>
