  \class QSGSimpleRectNode

  \brief The QSGSimpleRectNode class is a convenience class for drawing
  solid filled rectangles using scenegraph.
  \inmodule QtQuick

  \warning This utility class is only functional when running with the default
  or software backends of the Qt Quick scenegraph. As an alternative, prefer
  using QSGRectangleNode via QQuickWindow::createRectangleNode() or
  QSGEngine::createRectangleNode().
