László Németh 7d08767b89 tdf#130088 tdf#119908 smart justify: fix DOCX line count + compat opt. 
Writer typeset DOCX files with more lines/pages, because of
new default paragraph justification algorithm of MSO 2013 and
newer, which resulted in losing text layout interoperability
for new DOCX documents.

Add new compatibility option "JustifyLinesWithShrinking" to
store also the new type of justification in OpenDocument files.

First analysis of the unknown justification algorithm shows
up to 2% shrinking of plain justified line. Apply this value
to break the lines in the same (or very similar) positions
during importing a DOCX file with compatibilityMode >= 15
(created in MSO 2013 or newer), to avoid typesetting more lines
and pages.

Note: shrinking will be added by the next commits, fixing
the temporary exceeding lines.

Import Filters for LibreOffice Writer

The writerfilter module contains import filters for Writer, using its UNO API.

Import filter for DOCX and RTF.

  • Module contents

    • documentation: RNG schema for the OOXML tokenizer, etc.
    • inc: module-global headers (can be included by any files under source)
    • qa: cppunit tests
    • source: the filters themselves
    • util: UNO passive registration config

  • Source contents

    • dmapper: the domain mapper, hiding UNO from the tokenizers, used by DOCX and RTF import
      • The incoming traffic of dmapper can be dumped into an XML file in /tmp in dbgutil builds, start soffice with the SW_DEBUG_WRITERFILTER=1 environment variable if you want that.
    • filter: the UNO filter service implementations, invoked by UNO and calling the dmapper + one of the tokenizers
    • ooxml: the docx tokenizer
    • rtftok: the rtf tokenizer
