[Chameleon] textbutton label vertical align

[Paul Spencer]

Ken,

a fellow gentoo user!  I can see the problem you are having, it almost 
appears as if they are aligned at the top!

I'm running php 4.3.9 with gd 2.0.28 and freetype 2.1.9 with no problems 
like this, nor have I seen this problem on any system using freetype 
(the previous problems were related to the difference between TTF and 
freetype/GD1 and GD2)

You could try to debug this by looking in the file 
chameleon/htdocs/common/buttonizer/buttonizer.php

In the latest cvs version, the label vertical alignment is figured out 
around line 536-556.

You can run the web_buttonizer.php and turn on the debugging statements 
to get an idea of what is happening, or just add echos appropriately.

Cheers,

Paul
