Setting WA_TranslucentBackground after winid() is ineffective on Symbian.
Currently Symbian doesn't support semi-transparent EGL surfaces.
WA_TranslucentBackground attribute is ineffective if set after EGL
surface creation. To enable translucency in this case we need to
recreate backing store to get raster surface which supports translucency.
