To avoid of rivers and too much hyphenation, add minimum
and maximum word spacing options, similar to XSL-FO/CSS
and DTP software.
Only limiting hyphenation was implemented: hyphenation
of the words are disabled, if it's possible to expand
or shrink the spaces of the line within the values specified
by the maximum and minimum word spacing. First try to apply
the minimum word spacing, and if not possible, then the
maximum word spacing.
Note: maximum allowed shrinking has been applied for the
hyphenated lines instead of the minimum to remove the
hyphenation, yet. With the suggested default word spacing
values, this results no or minimal differences.
New UNO paragraph properties:
com::sun:⭐:text::ParaWordSpacingMinimum
com::sun:⭐:text::ParaWordSpacingMaximum
New ODF paragraph attributes:
loext:word-spacing-minimum
loext:word-spacing-maximum
New paragraph settings on Text Align pane:
Minimum word spacing
Maximum word spacing
While the desired word spacing got "Desired" label.
Note: suggested values of minimum, desired and
maximum word spacing are 80%, 100% and 133% (default
values e.g. in Adobe InDesign), in narrow columns e.g.
60%, 100% and 150%.
