PangoCairo: Create cairo_font_face_t using DirectWrite
...if Cairo is built with DirectWrite support. With this, we can
support colored Emoji, a long-standing issue, on Windows without needing
to use FontConfig, on Windows 8.1 or later, since DirectWrite added support
for colored Emoji starting with Windows 8.1.
This will really fix issue !302 completely, regarding the Emoji not
shown in color!
