It handles them fine, but as you have noticed it has to
rasterize them. This is because the filters basically can't
be mapped to any of the printing formats.

Only the filtered content should be rasterized.

The images should render at "printer resolution" what ever
the JDK thinks it is. Not that this really helps that much as
your 100MB files could easily blow up to 400MB.

Unfortunately filter-effects are problematic for printing
since they are more advanced then most back ends can handle.
The require conversion to dumb bitmaps...
