X-Git-Tag: fop-0_20_5rc~123
X-Git-Url: https://source.dussan.org/?a=commitdiff_plain;h=bfb92600b6d880678a236064d20eee95d9a4d32c;p=xmlgraphics-fop.git

Get logger from parent in FONode constructor. This allows logging
in FO constructors (except in fo:root).
Moved fo:marker handlich from FONode to FObj.
Create Hashtable for fo:marker lazily.
Removed unused method getNextPage() from AreaTree
