Subject: 1. TraitSetter modified to provide padding properties for regions.
X-Git-Tag: Root_Temp_KnuthStylePageBreaking~1044
X-Git-Url: https://source.dussan.org/?a=commitdiff_plain;h=a25886fa6eb7c702e71c46e2921e57c449344ee2;p=xmlgraphics-fop.git

1. TraitSetter modified to provide padding properties for regions.
2. PDFRenderer modified to take into account region borders and region padding
   when rendering text.  (Possibly temporary solution--may need to move code
   to base AbstractRenderer in future.)  Work incomplete--will need to also reduce
   line length accordingly to account for region borders and padding.
