Using this technique we can automatically register all necessary
revisions and minor versions of a type, using the metaobject system.
This greatly reduces the potential for mistakes and resulting
incompatibilities between versions of imports.
We assume that for each type we need to register all revisions of its
super types and its attached type, and that the revisions match. That
is, if you import version X of type A, you will also get version X of
its attached type and of any super types. As we previously didn't take
these dependencies into account when manually registering the types, a
number of extra revisions are now registered for some types.
Potentially, we can now generate the qmltypes files at compile time,
using moc.

From now on we prefer nullptr instead of 0 to clarify cases where
we are assigning or testing a pointer rather than a numeric zero.
Also, replaced cases where 0 was passed as Qt::KeyboardModifiers
with Qt::NoModifier (clang-tidy replaced them with nullptr, which
waas wrong, so it was just as well to make the tests more readable
rather than to revert those lines).

...and include a tab with custom OpenGL rendering. Tab widgets are
interesting because they are commonly used in applications in combination
with widgets like QOpenGLWidget and QQuickWidget, and because they typically
trigger rapid show-hide sequences which QQuickWidget does not always handle
as well as it could.
Thus this serves both as a helpful example and a useful testing tool.
Plus it exposes at least two bugs already, namely that the continuous
animation in the QQuickFBO does not start when switching to the tab
containing the QQuickWidget in question, and that it is impossible
to integrate third-party rendering code in a robust manner due to
QQuickWidget destroying everything whenever hiding the widget. This
is not what happens with a QQuickView and the normal render loops.

Following the qtbase fixes, start doing things correctly in the
QQuickWidget examples too. Remove the checkbox and use a --transparent
command line argument (like in hellogl2).
In addition --transparent --no_render_alpha can be used to verify the
most problematic case: when alpha is present and the backingstore contains
semi-transparent pixels in places where the underlying QOpenGLWidget is
opaque. Here the result must still be an opaque pixel. This was previously
ensured by a glColorMask call, now replaced by glBlendFuncSeparate in
QPlatformBackingStore.

Resolving happens after each rendering of the scene.
The blit to the temporary non-multisampled fbo could be avoided,
in theory, by sending the fbo instead of the texture id down the
stack and performing a blit directly to fbo #0. This however
involves a number of potential issues, for example due to the
non-sharability of FBOs between contexts. Hence it is left as a
future exercise.
