Subject: Fix for bad page-master and region margin calculations. All margin calculations now... 
X-Git-Tag: Root_Temp_KnuthStylePageBreaking~71
X-Git-Url: https://source.dussan.org/?a=commitdiff_plain;h=0e77a21e89c79f08a5f55f245081a767572279a4;p=xmlgraphics-fop.git

Fix for bad page-master and region margin calculations. All margin calculations now use margin-* attributes directly, ignoring start|end-indent and space-*.
Better check for borders and padding on regions.
