* This plugin will use YUV overlay if supported, using overlay will result in

* If YUV overlay is not supported this plugin will use RGB offscreen video
* surfaces that will be blitted onto the primary surface (display) to

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