[Qt] Handle the layers visible rect calculation on the web process.
Created attachment 119614 [details] Patch
This patch works but makes the desktop view not show any content unless we resize the view. This is caused by the layertreehost not receiving the first visible rect because AC had not been completely entered yet. I'll have to fix this after Christmas before pushing any of this. It would work previously since painting would update the visible rect later on.

Comment on attachment 122414 [details] Patch Wait... I think you uploaded the wrong patch to the wrong bug.
btw if you're adding files for TextureMapper, don't forget to add them to the EFL/GTK builds (just grep for TextureMapperNode.cpp)
Created attachment 122920 [details] Patch Updated patch after rebasing and splitting the LayerTransform part into bug #76291. Another patch will follow up to do a projection of the visible rect instead of mapping it like collectVisibleContentsRects was doing.

Humm we would still need a method to trigger the visible rect update that would then call the getter on the interface from each layer. The root cause is that layers can be created and added to the tree without the tree host knowing about them, and this method would have to be called instead of the setter in set/addChildren. Personally I prefer a straight setter for the rect and scale.
Comment on attachment 122920 [details] Patch Please fix variable name (I prefer m_pageVisibleRect or m_visibleRectInPageCoordinates) and maybe merge in patch 76541 before committing.

(In reply to comment #11) > Committed r105413: <http://trac.webkit.org/changeset/105413> It seems that this patch has broken something. I was running a layout test with: MiniBrowser --desktop 'file:///opt/git/webkit/LayoutTests/editing/selection/regional-indicators.html', and it was visible until the patch before this one (I have a release build). When I've applied this, then MiniBrowser usually loads but shows a blank page instead, I'm not sure what is going on. Even for "http://google.com" I still get nothing there. Running MiniBrowser without --desktop, I still shows a blank page, but it seems to show up when I refresh it. Any ideas?
