This adds window hints for the initial position, in screen coordinates, of a window. The special value GLFW_ANY_POSITION means the window manager will be allowed to position the window. It is not possible to set window positions on Wayland and GLFW will always behave as if these hints are set to GLFW_ANY_POSITION. Fixes #1603 Fixes #1747
