When WPEBackend-fdo >= 1.3.0 is detected, the threaded view now relies on the wpe_fdo_egl_exported_image API instead of the EGLImageKHR-based API which is going to be deprecated in 2.26. The GLib sources created by the view now use the default priority as well, the custom priority is no longer required.
