*****     failures from 'make test' of 5.2.12     *****
these types of problems keep recurring (since 2001) so it seems that
svn changes sometimes never make it to a stable release or there is no
co-ordination with gd developers to prevent them from popping up again.

i am normally happy with the centos lag away from fresh releases, but i
need at least 5.2.12 for nginx and that is why i am trying to compile
from source.

     1.) 'Bug #43073/#48732 (TrueType bounding box is wrong for
angle<>0) [ext/gd/tests/bug43073.phpt]';
     2.) 'Bug #48801/#48732 (Problem with imagettfbbox)
[ext/gd/tests/bug48801.phpt]'; also (maybe)
     3.) 'Test imagecolorallocate() function : usage variations  -
passing different data types to fourth argument

The bug occurs in the two PHP versions I have available to test on
here. Perhaps I can try on a win32 box when I get to work.

PHP 5.3.3-dev compiled from src
-------------------------------
GD Version: bundled (2.0.34 compatible)
Freetype Version: 2.2.1

./configure  --with-apxs2=/home/user/bin/httpd/bin/apxs
--prefix=/home/user/bin/php --with-pdo-mysql --with-zlib --with-gd
--with-gettext --with-freetype-dir --enable-gd-native-ttf



PHP 5.1.6 from centos rpms
--------------------------
GD Version: bundled (2.0.28 compatible) 
FreeType Version 2.2.1

------------------------------------------------------------------------

Which GD library do you use? Bundled?

------------------------------------------------------------------------

[2010-02-09 06:39:41] sks76543210 at gmail dot com

Description:
------------
imagettftext() and imagettfbbox() both return wrong bounding box if the
angle is not set to 0. This sounds similar to a bug closed last year at
http://bugs.php.net/bug.php?id=43073

See http://www.yessum.org/gdbug2/ for font and samples. This bug
appears to be in 5.1.6, and has since gotten worse in the latest svn. 

Also, in 5.3.3-dev, the text doesn't seem to even be on the same
baseline on many of the angles.

Reproduce code:
---------------
<?php
    $font = './cour.ttf'; // Courier New
    
    $im = imagecreatetruecolor(600, 600);
    
    imagefill($im, 0, 0, imagecolorallocate($im, 224, 224, 224));
    $black = imagecolorallocate($im, 0, 0, 0);
    $red = imagecolorallocate($im, 255, 0, 0);
    
    $angle = 0;
    do {
        $bbox = imagettftext($im, 16, $angle, 299, 299, $black, $font,
'The quick brown fox');
        imagepolygon($im, $bbox, 4, $red);
        $angle += 45;
    } while ($angle < 360);
    
    header('content-type: image/png');
    imagepng($im);

Expected result:
----------------
The bounding box should be a bounding box

Actual result:
--------------
The string is not contained in the bounding box.
