This PR introduces a gfxapi interface layer (Backend, IRenderWindow, Framebuffer, IGLContext, IGestureRenderer, IGraphicsDevice) and a concrete gfxOpenGL backend, replacing direct OpenGL/Qt-GL usage throughout the app and renderlib. It reworks GL-context ownership (new QtGLContext/RendererGLContext/HeadlessGLContext), moves the selection buffer into the gesture renderer, and routes framebuffer/clear operations through the new abstraction.
All opengl calls should now be inside of renderlib/gfxOpenGL, and all Qt dependencies removed from renderlib.
