Downloads the given texture pixels into a glib.bytes.Bytes. The rowstride will
be stored in the stride value.
This function will abort if it tries to download a large texture and
fails to allocate memory. If you think that may happen, you should handle
memory allocation yourself and use gdk.texture_downloader.TextureDownloader.downloadInto
once allocation succeeded.
