By taking things like the item width and height in updatePaintNode()
(while gui is locked).

Having rendernodes triggering fullscreen updates with the software backend
is not ideal. Therefore, introduce the option of reporting that the rendernode
is well-behaving, meaning it only writes inside the reported bounding rectangle.
Similarly, the OpenGL batch renderer can keep using the depth buffer when the
rendernode is known to behave like the renderer expects.

Have to change getResource() a bit since it turns out it is not suitable
currently for backends that do not have a per-window rendercontext and do
not implement the interface on the rendercontext. Pass in the window to
make sure it can always figure out which window we want the resources for.
(we do not want rendererInterface() to return window-specific instances
created on the fly, with ownership issues, so stick with the simple model
where backends implement the interface on one of their existing classes)
To support clipping, QSGRenderNode::RenderState is extended accordingly.
Also updated the docs since some claims in the rendernode docs are not true
since Qt 5.3.
