     * behavior as a result. For example, when used as GPU_COLOR_OUTPUT the buffer

     * will behave similar to a single-buffered window. When used with

     * COMPOSER_OVERLAY, the system will try to prioritize the buffer receiving

     * an overlay plane & avoid caching it in intermediate composition buffers.
