Ensure font is fetched from registry even when zoom levels match

The font returned by Font.win32_new is stored in the setFont() method of
widgets. Previously, if targetZoom == font.zoom, the passed font was
returned directly. However, the passed font could have been disposed by
user code. This change ensures that the font is always fetched from the
font registry, even when the zoom levels match, avoiding potential use
of disposed fonts.
