New FopImage interface - better separation between FOP core and r enderers

[Eric SCHAEFFER <ES...@Techmetrix.net>]

Hi,

I'm revisiting the FopImage interface. It (and other classes, it seems) uses
some classes from the datatypes package, like ColorSpace, or from the pdf
package (PDFColor). 

I think the ColorSpace class should be removed (I don't see why to use it),
and I want to remove any dependencies between FOP core classes and specific
renderer classes (like the use of PDFColor : that's the responsability of
the renderer to know how to translate the info into its destination
language, not the responsability of the image package).

Any comments ?

Eric.
