Description:
------------
//The function imagettbbox() always returns -1 for X coordinate left corner.

$bbox = imagettfbbox(20, 0, './arial.ttf', 'TestImagettfbbox');

echo $bbox[0]; // always -1 - lower left corner, X position
echo $bbox[6]; // always -1 - upper left corner, X position


//with this problem there is no way to align left the text in the image.

Test script:
---------------
$bbox = imagettfbbox(20, 0, './arial.ttf', 'TestImagettfbbox');

echo $bbox[0]; // always -1 - lower left corner, X position
echo $bbox[6]; // always -1 - upper left corner, X position


Expected result:
----------------
Return valid values for X coordinates.
I've tested the imagettbbox() in PHP 5.0.4 and the function is working.


Actual result:
--------------
imagettbbox() always returns -1 for X coordinate of the left corners.
