Bug #72604 (imagearc() ignores thickness for full arcs)
--SKIPIF--
<?php
if (!extension_loaded('gd')) die('skip requires ext/gd');

<?php
$im = imagecreatetruecolor(100, 100);

--EXPECT--
The images are equal.
Fix #72604: imagearc() ignores thickness for full arcs We remove the special casing for full arcs, what conforms to external libgd. 2016-07-15 17:42:26 +00:00			`--TEST--`

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.
