Starting from WPEBackend-FDO 1.6.x, software rendering support is available. This features allows wpesrc to be used on machines without GPU, and/or for testing purpose. To enable it, set the `LIBGL_ALWAYS_SOFTWARE=true` environment variable and make sure `video/x-raw, format=BGRA` caps are negotiated by the wpesrc element.
