This means that widgets application now need to setup the GL context
sharing as well. QWebEngineWidgets::initialize() must be called,
which has the same effect as QWebEngine::initialize().
The QtWebEngineWidgets now depends on the QtWebEngine module to make
this happen.

Since QOpenGLWidget is only available in Qt 5.3, this patch also
disables the webenginewidgets module completely when building using
Qt 5.2.

This is a gross mechanical modification of the documentation, along with build
system bindings to allow it to generate. This should allow doing iterative
improvements to the documentation from now on.

This fixes project-related qdoc warnings but we still need to do some serious
work to get the documentation better fitting QtWebEngine. All the documentation
is ported to match the current state of our headers (without trying to adapt
to modified APIs yet) and we should clear the part of the documentation that we
don't need at the same time that we clean up our public headers.

To match other modules example directory structures we should deploy our
examples in a directory matching the module name, webengine and
webenginewidgets in our case.

qmake uses the relative directory of each example up to the upper "examples"
directory to decide where they will be deployed when running the sources
install target.
