OK - so you have this nice crisp screen, and still you want to add extra monitors to the laptop! That means Blender should switch back and forth to HiDPI modes, when you move a window to another monitor. This code makes the pixelsize scale factor a window property, and handles an event when a window moves to another monitor. It then changes the native pixelsize nicely and refreshes entire UI. You can also have one Blender window on high, and other on low resolution. Stretching a Blender window from 1 monitor to the other works too, but that is Apple magic handling it.
