    Description

      In the past, if I specify openGL version to 3.0 to the default QSurfaceFormat object, the opengl context of the quick window would be a 3.0 context in a GLES 3.0 capable iphone (iphone 5S +).
      Since qt-iOS 5.5.0, it will create an openGL 2.0 context even if I have requested a 3.0 context.
      The sample program to reproduce this issue was attached.
