User config file currently discarded

[Vincent Hennebert]

Hi,

By trying to debug my FOrayFont adaptation I noticed that the user config file 
currently isn't taken into account by the Trunk.

The apps.FOUserAgent.getConfig() method is actually never called within the 
code, and (as a consequence I suppose) neither is the 
PDFRenderer.configure(Configuration) method, whose purpose is among other things 
to register fonts specified in the user config file.

Is there a particular reason for this situation? A simple fix would be to call 
configure within the AbstractRenderer.setUserAgent method, where we can get the 
user config file associated with the UserAgent given as parameter.
This is perhaps not the right place to do that? But if it's ok I can provide a 
patch.
