    Description

      Running

      QT_QUICK_BACKEND=software ./simplebrowser

      results in a segfault.

      Reverting the qtdeclarative patch https://codereview.qt-project.org/209630 fixes the issue. This patch changes the software backend to assume that image nodes always have a texture, but in DelegatedNodeTreeCreator::setupRenderPassNode we sometimes create image nodes without textures. This leads to a null pointer dereference in qsgsoftwarerenderablenode.cpp:155.
