Modified: src/java/org/apache/fop/area RegionViewport.java
src/java/org/apache/fop/layoutmgr PageLayoutManager.java
src/java/org/apache/fop/render/pdf PDFRenderer.java
Log:
1. PDF block background rendering properly offset to account for region
borders and padding.
2. Helper methods added to RegionViewport for quickly determining region
margins, useful for render.* and layoutmgr.* classes.
