  25  * Preamble:
  26  *
  27  * This plugin will use YUV overlay if supported, using overlay will result in
  28  * the best video quality (hardware interpolation when rescaling the picture)
  29  * and the fastest display as it requires less processing.
  30  *
  31  * If YUV overlay is not supported this plugin will use RGB offscreen video
  32  * surfaces that will be blitted onto the primary surface (display) to
  33  * effectively display the pictures. This fallback method also enables us to
  34  * display video in window mode.
