w32_common: center window on original window center on resize to fit screen 

Center the window on the original window center instead of the screen center
when the window has been resized due to requested window size exceeding the
size of the screen.

If user moved the window, he probably did it for the reason and he probably
don't want it to get back to the center of the screen when he is resizing it
(with window-scale for example).
