Make _gdk_win32_display_get_monitor_scale_factor() less complex, by: * Drop the preceding underscore. * Dropping an unused parameter. * Using a GdkSurface instead of a HWND, as the HWND that we pass into this function might have been taken from a GdkSurface, which are now always created with CS_OWNDC. This means if a GdkSurface was passed in, we ensure that we only acquire the DC from the HWND once, and do not attempt to call ReleaseDC() on it. * Store the HDC that we acquire from the GdkSurface's HWND into the surface, and use that as the HDC we need for our GdkGLContext. * Drop the gl_hwnd from GdkWin32Display, as that is really should be stored in the GdkSurface. * For functions that were updated, name GdkWin32Display variables as display_win32 and GdkSurface variables as surface, to unify things. * Stop calling ReleaseDC() on the HDC that we use for OpenGL, since they were acquired from HWND's created with CS_OWNDC.
