      Description

      Hey all,
      in relation to QTBUG-45058 and QTBUG-45930, I need to report 3 issues about the usage of deferred rendering inside a Scene3D element.
      These are on GIT as of today.

      1- the whole scene is flipped upside down
      2- alpha pre-multiply is not solved in this case (see screenshot)
      3- the example produces the following error message:
      Qt3D::QPointLight::setProperty: Property "positionTransformed" invalid, read-only or does not exist

      Attached, a modified version of the deferred-renderer-qml example.
      I only added a plane to show the alpha issue and changed main.cpp to load a Scene3D
