win32 font is very small if the lfHeight of HFONT is exactly -size

cairo_win32_font_face_create_for_hfont is reusing the HFONT object
passed by an argument if possible to create a scaled font. However,
the condition was wrong. It checked the font matrix scale factor is
`-lfHeight`. But it should be `-lfHeight * WIN32_FONT_LOGICAL_SCALE`.

Fixes cairo/cairo#3
