The linux port is not exported.  On the windows port, the entire class is
exported.  Is it worth just exporting the whole class, to mirror the windows
behaviour?

   static BitmapPlatformDevice* Create(CGContextRef context,
                                       int width, int height,
                                       bool is_opaque);
