annotate libgui/graphics/Backend.cc @ 27316:22265a75be74

eliminate static instance of Qt graphics ObjectFactory class * Backend.h, Backend.cc (Backend::m_factory): New member variable. Backend object now owns the ObjectFactory. (Backend::Backend): Create ObjectFactory here. (Backend::~Backend): Delete it. * ObjectFactory.h, ObjectFactory.cc (ObjectFactory::instance): Delete. (ObjectFactory::ObjectFactory): Now public.
