Description:
------------
Text created with imagettftext() has kerning (letter-spacing) errors

Reproduce code:
---------------
Please see http://www.yessum.org/gdbug/ for example images, fonts used, and sample php script. Entire test case is tar'ed at http://www.yessum.org/gdbug.tar.gz

In PHP 5.1.6, with GD version "bundled (2.0.28 compatible)", the test images did not have any kerning errors.

In the php5.3-201002071530 snapshot with GD version "bundled (2.0.34 compatible)", the text on the images is not displayed properly, especially evident in http://www.yessum.org/gdbug/scriptina-php-5.3.3-dev-gd-2.0.34.png but there are less noticeable errors in http://www.yessum.org/gdbug/times-new-roman-php-5.3.3-dev-gd-2.0.34.png as well.

Expected result:
----------------
imagettftext() should continue displaying text as it did in PHP 5.1.6 with GD 2.0.28

Actual result:
--------------
imagettftext() has kerning errors making the text completely illegible in some cases
