href="show_bug.cgi?id=140731">tdf#140731</a>: sw transliteration: avoid too many redlines
As a workaround for the performance regression
from commit 2d3c77e9b10f20091ef338e262ba7756eb280ce9
(<a class="bz_bug_link
bz_status_VERIFIED bz_closed"
title="VERIFIED FIXED - EDITING: Record Changes feature does not record changes to letter case with Shift+F3, 'Cycle Case', 'tOGGLE cASE' shortcuts"
href="show_bug.cgi?id=109266">tdf#109266</a> sw change tracking: track transliteration),
switch off redlining to avoid ~freezing, if a single
transliteration could result too many (>~500) redlines.
A single transliteration creates n redlines
for n paragraphs of the selected text, except in
the case of transliterating to title case, where it
creates n redlines for n words. It's very easy
to freeze Writer, because Writer's slowing down with
n redlines is described by an O(n²) (quadratic) time
complexity. Eg. in an experiment, title casing
~660 words was 6 sec, but ~3000 words was 85 sec,
regarding to creating 660 vs 3000 redlines.
Note: this is a partial revert of commit
2d3c77e9b10f20091ef338e262ba7756eb280ce9, if the
selection contains more than 500 paragraphs (or in the
case transliterating to title case, ~500 words).</pre>
