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.

Qt copyrights are now in The Qt Company, so we could update the source
code headers accordingly. In the same go we should also fix the links to
point to qt.io.

Remove the red rectangle.
Change the background color to a gradient. (taken from rendercontrol)
Disable the transparency checkbox everywhere but Linux since it
usually will not work. (too much hassle with platform specifics like
frameless windows, etc.)

And make qquickviewcomparison able to demonstrate how to create a
partially transparent QQuickWidget.
Avoid also recreating the QQuickView/QQuickWidget multiple times
when switching between the radio buttons.
[ChangeLog] Added QQuickWidget::setClearColor() in order to support
semi-transparent QQuickWidgets.

Besides serving as a side-by-side test tool for QQuickView and
QQuickWidget (including multisampling), it also demonstrates some
useful practices for rendering 3D content via QQuickFramebufferObject.
