Reset the internal OpenGL states so that the target is ready for drawing.
This function can be used when you mix DSFML drawing and direct OpenGL
rendering, if you choose not to use pushGLStates/popGLStates. It makes
sure that all OpenGL states needed by DSFML are set, so that subsequent
draw() calls will work as expected.
