+ * operations are compared against those produced by a correctly
+ * functioning X11 backend (and X11 server).
+ *
+ * Obviously, only the most basic operations reasonably be expected to
+ * produce pixel-by-pixel identical results as the X11 backend. We
+ * don't even try to test the correctness of ellipses, tiles or
+ * stipples. Not to mention fonts.
+ *
+ * But, for those operations we do test, we should try to test quite
+ * many combinations of parameters.
+ *
+ * This is just a quick hack, and could be improved a lot. There are
+ * copy-pasted code snippets all over that need to be factored out
+ * into separate functions.
