When formatting a 180k char Writer paragraph, most of the time is spent in vcl::ScriptRun::next(), which is called twice per line from SwTxtGuess::Guess(), once via GetTxtBreak() and once via GetTxtSize(). In the second call, from GetTxtSize(), the end position of the line is known, and passed to vcl, and iterating beyond that position seems pointless. This reduces vcl::ScriptRun::next() from 24 to 11 billion callgrind cycles when built with GCC 4.9.2 -m32 -Os. Change-Id: Ia23fcccaf5ef9c9ecdcb54bfc8f0f8a043c8711e
