title: Skia vs Cairo vs Direct2D, which is the most feature rich?
body: <p>A just curious question. <br>
  I'm aware that: <br>
  Skia, Cairo: library <br>
  Direct2D: API <br>
  But without any additional components, exclusively on <b>Windows</b> platform, which bears the most features? I'm not talking about performance or programming simplicity. <br>
  Is there any possibility that Cairo could use D2D as the rendering backend on Windows platform?</p>
