Description:
------------
In the test script below, 'a' indicates an input variable that governs the angle at which the text should be rendered. The test script below renders fine for a=0. But as you increase a, the letters in the text become progressively out of alignment until by a=60 the baseline is completely distorted. By a=160, letters actually overlap.

This problem does not occur on PHP 5.2.6 (in our production environment).


Test script:
---------------
$image = imagecreatetruecolor(500, 500);
$bgcolor = imagecolorallocate($image, 255, 255, 255);
imagefill($image, 0, 0, $bgcolor);

$edgecolor = imagecolorallocate($image, 63, 63, 63);

imagefttext($image, 30, $_GET['a'], 250, 250, $edgecolor, './arial.ttf', 'Services');

header ('Content-type: image/gif');
imagegif($image);


Expected result:
----------------
Expect text to render correctly at all angles.

Actual result:
--------------
Text becomes distorted as angle changes from 0.
