HiDPI compatibility

Windows, Windows applications, Java applications, sites, etc need may or may not be HiDPI aware. The issue with browsers is just about images that may (and one day will) be better for high resolution clients. The issue with OS and application are more painful. A lot of application just not usefull anymore on 15″ 4K display. OS trying too zoom Windows application to work with high DPI. For some it works, for some not.
