Re: problem in firefox and moziila

Hi, Jhon-

I put together a (very) simple example of how you can do text-wrapping 
with script.  I tested in in Windows with FF2, Opera9, and IE7+ASV3.

http://svg-whiz.com/svg/text/TextWrap-simple.svg

It's by no means perfect... it does take into account text-anchor, but 
not letter-spacing, word-spacing, etc.  The heuristic for determining 
the width of each line is a weak ad-hoc measure based on the number of 
characters and the font-size, not the getComputedTextLength or getBBox, 
because those didn't work (for this purpose) in FF2.

Still, I hope it's of some use to you.  To use it, simply create a 
'textArea' element in my pseudo-SVG1.2 namespace, with the desired 
dimensions and text, and this script will do pretty much the rest.  You 
can use whatever attributes you want (it will transfer them over), but 
keep in mind that this script is not rigorously tested.

You could adapt it to be more robust, but I'm hoping the real 
'svg:textArea' element is implemented in browsers before long, making 
this script unnecessary.
