 * Preamble:
 *
 * 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.
