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.

When e.g. growing the size of the border image in an animation,
we would not get updates of the paint nodes when the size was
so small that the bounded target rect and source rect did not
change (when the size was smaller than the sum of the borders).
Since this can happen, we also need to detect when the size
changes and update the node for this case.

While we protected against the the borders exceeding the size of
the source image when deciding whether to create a given patch,
we did not protect against the case where the target rectangle
is smaller than the borders. To fix this, we simply move the
calculation of the target rectangle up to before we create the
nodes, and check for isEmpty() before creating the nodes.

In addition, we did not properly handle changing the borders
dynamically. The subtree has to be rebuilt if the borders change
so that the source or target rectangles change.

Reviewed-by: Gunnar Sletta <gunnar@sletta.org>

Keeping all patches of the border image in the same texture
with different sample points can cause parts of the border
to bleed over to the center patch. To rectify this, we
create a separate texture for each of the nine patches we
need, and separate image nodes.

To avoid applying antialiasing on the interior edges of the
border image, we introduce new antialiasing flags which can
be used to specify precisely which edges of the image should
be antialiased.

[ChangeLog][BorderImage] Fixed possible pixel bleed between
border patches and center patch in BorderImage.

See the task for the full reasoning behind this patch.

The threaded renderloop has been refactored to have one window per
thread. This is mostly a simplification of the current code path where
for loops over multiple windows are turned into if (window).

The QSGContext has been split into two classes, QSGRenderContext
for which there is one per OpenGLContext.

The rest of the patch is name changes and a couple of cleanups
in the hopes of simplifying this change.

A texture based node without a valid texture is not allowed,
as the material and the renderer will only tolerate
well-formed nodes. If a node is missing any part of its material
state it should not be in the scene graph in the first place.

Because of an "optimization" in QSGDefaultImageNode::setTexture
and QSGSimpleTextureNode::setTexture, we must temporarily set
the texture to 0 to ensure that it gets updated properly. This
temporarily puts the node into an invalid state which can lead
to crashes when QSGNode::markDirty() reaches the renderer.

qtqml.qdocconf and qtquick.qdocconf now refer to the correct
snippets and source directories.

Snippet paths in .qdoc and .cpp files have been updated to refer to
the new shortened path references, e.g. \snippet qml/file.cpp instead of
\snippet doc/src/snippets/qml/file.cpp.

This also deletes snippets from src/qml/doc/snippets that belonged under
src/quick/doc/snippets (and were already duplicated there anyway) and
restores some snippet files that shouldn't have been deleted.

Also fixes some inline snippets to use \code .. \endcode instead of
\qml .. \endqml as they contained javascript or partial QML
snippets that were causing parsing errors from qdoc.

There are still snippet errors arising from qmlintro.qdoc as the
qmlintro snippets directory that it refers to cannot be located.

There are also two references to a removed snippet identifier in
examples/qml/cppextensions/plugins/plugin.cpp that need to be fixed
in conjunction with the related docs in a later commit as the relevant
code has changed and the docs are now invalid.
