Bug description:imagettfbbox/imagettftext "Could not read font" error

Description:
------------
Using the Vera.ttf font, which is part of the Image_Text PEAR package
results in an odd error...

The font can be found here:

http://svn.php.net/viewvc/pear/packages/Image_Text/trunk/tests/Vera.ttf?view=log

The error given by imagettfbbox() is "Could not read font".

When tested with is_readable(), the font is indeed readable.

When opening the Vera.ttf font file in windows, it produces the following
error:

"The requested file Vera.ttf was not a valid font file."

It would appear that the file may well be corrupt, not that it "could not
read".

This error lead to a very confusing situation...

I propose that the error should be more descriptive.

Instead of "Could not read font", consider "Invalid font file".

Test script:
---------------
<?php

$font = 'Vera.ttf';
$test = imagettfbbox(10, 10, $font, 'test');
echo "\n<br>What PHP version? ".phpversion();
$read = file_exists($font)?'Yes':'No';
echo "\n<br>Does font '$font' exist? ".$read;
$read = is_readable($font)?'Yes':'No';
echo "\n<br>Is font '$font' readable? ".$read;

?>

Expected result:
----------------
Warning: imagettfbbox() [function.imagettfbbox]: Could not read font in
/home/share/www/dev/test/php/imagettfbbox.php on line 4

Actual result:
--------------
Warning: imagettfbbox() [function.imagettfbbox]: Could not read font in
/home/share/www/dev/test/php/imagettfbbox.php on line 4

What PHP version? 5.2.13
Does font 'Vera.ttf' exist? Yes
Is font 'Vera.ttf' readable? Yes
