[PATCH 0/2] ui/gtk: Add keep-aspect-ratio and scale option

[Weifeng Liu]

Add these options to give users more control over behaviors in gtk
display backend:

- keep-aspect-ratio: when set to true, if the aspect ratio of host
  window differs from that of guest frame-buffer, padding will be added
  to the host window to preserve the aspect ratio of guest frame-buffer.

- scale: allow user to set a preferred scale factor, which would be
  helpful for users running on a hi-dpi desktop to achieve pixel to
  pixel display.
