New Revision: 677204
URL: http://svn.apache.org/viewvc?rev=677204&view=rev
Log:
Renamed "iform" package to "intermediate" (iform was too cryptic for my taste)
Changed IFRenderer to work against the IFPainter interface.
Started IFPainter implementations for the IF format (IFSerializer), SVG 1.1 and SVG Print. They currently support very simple FOs only (like examples/fo/basic/simple.fo).
