The new documentation style for publishing docs under qt.io
requires dedicated div classes for pages that use a three-
column layout.

The new divs enable the columns to stack and react to changes
in the window width.

The new implementation is much too slow because it will cause each
section of the border image to be uploaded to the atlas, and it will
not be shared between different border images nor between different
sizes of the border. The performance regression is so significant
that it's not worth it for the original bug fix.

We leave the tests around, so some of those might regress due to
this.

The previous code was wrong, as it cleared focus from the active
focus item directly. By doing so we would only clear focus inside
the focus scope that surrounded the item, but leave the scope itself
with active focus (which would then be the focus object). The intended
result is rather to end up with the root as focus object.

When having e.g. a clip node inside another clip node and adding
children to the innermost, we would get into the situation where
we did a partial rebuild for the outermost root, but its available
render order count would not be updated to reflect the change
deeper down in the tree. Since the z range would be based on the
outermost batch root's knowledge of the maximum render order in
the tree, what would happen is that the z of the rendered nodes
would increase steadily until they went outside of the viewing
volume and disappeared.

When decreasing the available order count of a batch root, we need
to also decrease the available order count of its parents. If any
of them drop below zero, we need to rebuild the render lists.

adding many new nodes to the tree.

Instead of using a cursor width of null when a cursor

This solves the issue of the new TextMetrics type's documentation not

Having a retina and non-retina screen connected resulted in getting
no output from QQuickRenderControl and QQuickWidget on the
non-retina screen.

This is caused by the fact that Quick is blindly calling
QWindow::devicePixelRatio(). This approach is wrong when using
QQuickRenderControl since the QQuickWindow does not have an actual
native window and so devicePixelRatio() merely returns some default value
which will definitely be wrong for one of the screens.

The patch fixes the problem by introducing
QQuickWindow::effectiveDevicePixelRatio(), which, via
QQuickRenderControl::renderWindowFor, supports the redirected case too.

The hit testing won't work very well with the upcoming patch that
changes which items that can be ignored.
(basically it doesn't consider the isAccessible flag,
so childAt_helper might return a node that was supposed to be ignored)

Earlier this was a sensible optimization in order to avoid too many heap
allocations and deallocations of interfaces, but these are cheap now, so
we can do it the do it the 'proper way' (i.e. before this patch we
didn't respect the a11y hierarchy as given by QAccessibleInterface
child() and parent(). This also uses the QAccessibleInterface::rect()
directly now instead of using the itemScreenRect() function, which
was shared between QAccessibleQuickWindow and QAccessibleQuickItem.

Since this changes the order of child interfaces to paint order (i.e.
second child interface is on top of first child interface), we need to
ensure that we hit test child interfaces in the correct order.
They should now always be processed with the last interface first, and
then return as soon as something is hit.

later as a result of frameSwapped. For the benchmark in question this
