A picture is worth a thousand message digests The bundled GD test suites makes heavy use of md5() to verify the result of drawing operations. This leads to fragile tests (even a slight change in a PNG header would cause failure, and of course there is the possibility of collisions), and even worse, eventual test failures are rather unrevealing. Therefore we replace all md5() verification with a simplistic test_image_equals_file(), which is basically a simplified port of libgd's gdTestImageCompareToFile(), adapted to the needs of PHPTs. In the long run better tests helpers should be introduced (see also <http://news.php.net/php.internals/94081>), but for now this solution is preferable over the former.
