Actually 0.20.5 supports direct embedding of TIFF in PDF as well. This 
is a very important feature for our application as we have lots of TIFF 
images (actually incoming faxes) which we bundle into PDFs using FOP. 
Would hate to see that getting lost in the trunk code. Not sure how 
this could be done with the Batik stuff as the PDF renderer would need 
access to the undecoded stream in that case.
