This will cause a pixbuf loader to parse the next @count bytes of
an image. It will return %TRUE if the data was loaded successfully,
and %FALSE if an error occurred. In the latter case, the loader
will be closed, and will not accept further writes. If %FALSE is
returned, @error will be set to an error from the #GDK_PIXBUF_ERROR
or #G_FILE_ERROR domains.
