Balance word spacing within the consecutive lines to get uniform grayness and less rivers for better readability, enabled by the new paragraph property com::sun::star::text::ParaComposer and the following developments: * Add Paragraph Composer checkbox on Alignment pane of the paragraph formatting dialog window (not default yet); * Implement paragraph composer: big word spacing of a line is decreased by shifting the last word from the previous line, only if the word spacing is better, than before, and the increased word spacing in the previous line doesn't exceed the Maximum word spacing (limited paragraph composer); * When Maximum word spacing is not greater than the Desired word spacing, shifting of the last word is not limited by the Maximum word spacing (unlimited paragraph composer) * Add loext:paragraph-composer attribute, as LibreOffice ODF extension; * Add ODF unit tests for the limited and not limited paragraph composer. Note: "Smart justify" line breaking algorithm chooses space shrinking (limited by Minimum word spacing) only if shifting the last word isn't better based on the desired word spacing. This was still a greedy line breaking algorithm, resulting big word spacing in the lines before a longer word. The paragraph composer shifts the last word (or the first part of the hyphenated last word) from the previous line to decrease big word spacing in the actual line. Note: balancing very big word spacing in narrow consecutive lines can result vertical rivers. To avoid this, use limited paragraph composer by setting maximum word spacing. Follow-up to "smart justify", word spacing, letter spacing and glyph scaling developments.

Edit Engine
In OpenOffice.org build DEV300m72 this module was split off from svx but it
has no dependencies on svx (nor on sfx2) while in turn svx depends on editeng

If you build LibreOffice with dbgutil, you have some extended debug keys:
- Ctrl+Alt+F1 - draws the paragraph rectangles in different colors
- Ctrl+Alt+F11 - toggles dumping the edit engine state to the "editenginedump.log" on draw
- Ctrl+Alt+F12 - dumps the current edit engine state to "editenginedump.log"
