\class Qt3DRender::Scene3DItem
\internal
\brief The Scene3DItem class is a QQuickItem subclass used to integrate
a Qt3D scene into a QtQuick 2 scene.
The Scene3DItem class renders a Qt3D scene, provided by a Qt3DCore::QEntity
into a multisampled Framebuffer object that is later blitted into a
non-multisampled Framebuffer object to be then rendered through the use of a
Qt3DCore::Scene3DSGNode with premultiplied alpha.

\class Qt3DRender::Scene3DRenderer
\internal
\brief The Scene3DRenderer class takes care of rendering a Qt3D scene
within a Framebuffer object to be used by the QtQuick 2 renderer.
The Scene3DRenderer class renders a Qt3D scene as provided by a Scene3DItem.
It owns the aspectEngine even though it doesn't instantiate it.
The render loop goes as follows:
\list
\li The main thread runs, drives Animations, etc. and causes changes to be
reported to the Qt3D change arbiter. The first change reported will cause
the scene3drenderer to be marked dirty.
\li The QtQuick render thread starts a new frame, synchronizes the scene
graph and emits afterSynchronizing. This will trigger some preparational
steps for rendering and mark the QSGNode dirty if the Scene3DRenderer is
dirty.
\li The QtQuick render loop emits beforeRendering. If we're marked dirty or
if the renderPolicy is set to Always, we'll ask the Qt3D renderer aspect to
render. That call is blocking. If the aspect jobs are not done, yet, the
renderer will exit early and we skip a frame.
\endlist
The shutdown procedure is a two steps process that goes as follow:
\list
\li The window is closed
\li This triggers the windowsChanged signal which the Scene3DRenderer
uses to perform the necessary cleanups in the QSGRenderThread (destroys
DebugLogger ...) with the shutdown slot (queued connection).
\li The destroyed signal of the window is also connected to the
Scene3DRenderer. When triggered in the context of the main thread, the
cleanup slot is called.
\endlist
There is an alternate shutdown procedure in case the QQuickItem is
destroyed with an active window which can happen in the case where the
Scene3D is used with a QtQuick Loader
In that case the shutdown procedure goes the same except that the destroyed
signal of the window is not called. Therefore the cleanup method is invoked
to properly destroy the aspect engine.

\class Qt3DRender::Scene3DSGMaterial
\internal
\inherits QSGMaterial
\brief The Scene3DSGMaterial class is a custom QSGMaterial subclass used to
render a Scene3DSGNode
The Scene3DSGMaterial class renders a texture using premultiplied
alpha unlike the QSGSimpleTextureMaterial.
This is needed to properly integrate alpha blending from a Qt3D scene
within a QtQuick 2 scene.

\class Qt3DCore::SCene3DMaterialShader
\internal
\brief The Qt3DRender::Scene3DSGMaterialShader class is a custom
QSGMaterialShader subclass instantiated by a Qt3DRender::Scene3DSGMateria1
The Qt3DRender::Scene3DSGMaterialShader provides a shader that renders a texture
using premultiplied alpha.

\class Qt3DCore::Scene3DSGNode
\internal
\brief The Qt3DCore::Scene3DSGNode class is a simple QSGeometryNode subclass that
uses a Qt3DCore::Scene3DMaterial
The Qt3DCore::Scene3DSGNode allows to render a simple rectangle textured with a
texture using premultiplied alpha.
