Description:
------------
The ImageTTFText function produces no result, but also no  
error. I've tried several font files (Microsoft TT core 
fonts and also from other sources), several paths (the  
same dir as the PHP script, relative to DocRoot, absolute 
path a.s.o.).  
  
It looks like not calling imagettftext - the function  
silently does nothing...  
  
I have Debian "Woody" with Apache 1.3.29 / PHP 4.4.0. The  
GD lib is the bundled one (phpinfo says: "2.0.28  
compatible"). The Freetype lib version is 1.4pre, as  
provided from Debian package manager. 
 
PHP configure options: 
 
'./configure' '--with-apxs=/var/www/bin/apxs' 
'--with-mysql' '--enable-ftp' '--enable-shared' 
'--with-iconv' '--with-gd' '--with-curl' 
'--with-jpeg-dir=/usr' '--with-png-dir=/usr' 
'--with-dom=/usr' '--with-zlib' '--enable-cli'  
'--with-ttf=/usr'

Reproduce code:
---------------
<?php
header("Content-type: image/png");
$im = imagecreatetruecolor(400, 30);
$grey = imagecolorallocate($im, 102, 102, 102);
$white = imagecolorallocate($im, 255, 255, 255);
$red = imagecolorallocate($im, 255, 0, 0);

imagefill($im, 0, 0, $grey);

$fontfile = realpath("./Arial.ttf");

imagettftext($im, 20, 0, 10, 20, $white, $fontfile, "Hello World!");

imagepng($im);
imagedestroy($im);
?>

Expected result:
----------------
Displays an image with white-colored text "Hello World" in 
Arial font face on grey background.  

Actual result:
--------------
Displays an grey-colored image without any text (empty  
grey box). No error messages.
