Bug description:imagettftext and rotated text uses wrong baseline (regression)

Description:
------------
imagettftext and rotated text by e.g. 90 degrees aligns text on top of
characters instead of baseline.

The regression was introduced with commit
r293268  | tabe       | 2010-01-08 13:18:52 | Bug #49600 (imageTTFText text
shifted right) - fix difference of horizontal position between
imagettftext() and imagettfbbox()


Test script:
---------------
<?php
$img = imagecreatetruecolor(23, 100);
$col = imagecolorallocate($img, 255, 255, 255);
imagettftext($img, 8, 90,  10, 90, $col, "verdana.ttf", "foo bar qux");
imagepng($img, "img.png");


Expected result:
----------------
Normal text rotated by 90 degrees

Actual result:
--------------
Text rotated but aligned at top of characters instead of bottom
