Re: Pango: Convert logical width to x coordinate width ?

I think that my previous question could be summarised as "what is logical width" ? And I think the answer is "pixels" :-)
I generally recieve SVG files exported in centimetres, and this is what the coords I posted previously are (with a filter on the export).  Exporting in pixels are 1:1 gives a clearer example:
<text x="149" y="210" fill="#3E555F" font-weight="normal" font-size="24" font-family="Aachen BT">SPORTS CLUB NAME</text>
Calling the font-size of 24 against pango_layout_get_size (with the text above) gives back a logical width of 234.  Dividing this by half = 117.  Adding 117 to 149 gives 266, and so when I adjust the alignment::
<text x="266" y="210" fill="#3E555F" font-weight="normal" font-size="24" font-family="Aachen BT"
It gives exactly the same SVG file!

Subject: Pango: Convert logical width to x coordinate width ?

Greetings All,
I am using pango_layout_get_size to get the width of some text I have layed out (i.e. text, font and font size) this gives me back (according to the docs) the "logical width." of the text. 
What I want to do is convert this to x coordinates that would then work with SVG markup.  I believe that SVG xy coordinates a fairly similar to html, so I just thought somebody might have thought about this before. 
For example if I had::
<g><text x="2639.1" y="3865.21" fill="#CF352D" font-weight="normal" font-size="1467" font-family="Aachen BT">SPORTS CLUB
And I called pango to get the "logic width" of the text I get 8250.  I want to adjust the x attribute by half of the "x-width" of the text, but obviously 4125 is too large, but something like half of this would be close.  Unfortunately I need it to be exact.
Any suggestions are greatly appreciated :-)
