[xsl] Saxon Extension for Guessing Composed Text String Length

[Eliot Kimber <ekimber@xxxxxxxxxxxxxxxxxxx>]

I have implemented a simple Saxon extension function, 
renderedTextLength(), that lets you calculate the composed length of 
short text strings in XSLT. This is intended primarily to enable crude 
text fitting in FO-generating XSLTs. The accuracy is inherently limited 
because there's no way for my code to account for the effects of 
kerning, text sequeezing, justification, and so on, but it's good enough 
to allow, for example, setting the width of list labels to the length of 
the longest term in a definition list.

The files are provided under the GNU LGPL license.

(This may require you to register on the Web site, for which I 
appologize in advance.)

Cheers,

Eliot
