Subject: [PATCH] win32: Set the resize flag to match the SetWindowPos() flags

Incorrectly setting this when only changing the window position can early-out of the WM_DPICHANGED handler, and prevent the window size from being properly adjusted when moved between displays with a different scale factor.
