Plugins and dependend code

[Ferdinand Soethe]

Working on the FOP-Update I started wondering, why 
stylesheets and libraries for the pdf-output-plugin are 
placed in core instead of the plugin directory.

If it was placed in the plugin-dir one could easily change 
back between fop 0.2 and fop 0.94 by simple changing the 
line in forrest.properties.

Is there a way to do this. Can a plugin have it's own libraries?

wdyt?
