/* This program is intended to be used to validate the correctness of
* the basic graphics operations in a GDK backend. The results of the
* 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.
