Fix bug on X11 with WA_TranslucentBackground and native child windows.
The native child windows need to inherit the parent's visual in order
to have a translucent background as well.
Surface with type QSurface::OpenGLSurface should not be forced to use
the parent window's visual - the parent visual for instance, might not
even be GL capable.
Changing WA_TranslucentBackground during runtime is not supported, for
two reasons:
1) Other platform plugins seem not to support it
2) It would require recreating X windows.
Task-number: QTBUG-29625
