Fix up flawed TranslucentBackground usage in docs and examples
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.
