This adds the GLFW_SCALE_TO_MONITOR window hint for automatically resizing the content area of a window to the requested size times the monitor content scale each time it is placed on a new monitor. This only applies to windowed mode windows and includes the initial placement at window creation. This hint only has an effect on platforms where screen coordinates and pixels always map 1:1 such as Windows and X11. Platforms like macOS instead change the resolution of the framebuffer independently of the window size. Related to #676. Related to #1115.
