Minimum required Windows version is XP again (instead of Win10). Win_GetWindowScalingFactor() tries to use two dynamically loaded functions from newer windows versions (8.1+, Win10 1607+) and has a fallback for older versions that also seems to work (at least if all displays have the same DPI). Moved the function to win_main.cpp so the dynamically loaded functions can be loaded at startup; so edit_gui_common.cpp could be removed again.
