Version 1.0.14: crash fix in text rendering. 

Fix a regression introduced in 8d354382a4 which caused an overflow
in _parAnalysis access. We were resizing _parAnalysis array for a
line width without the pending newline character while we used it
for painting a line including the pending newline character. It was
not a problem before, when we were trimming them from the end of
the string, but it results in a buffer overflow and crashes in the
lastest versions. So now we just don't include the newline in the
painted string, so it has exactly the same size as _parAnalysis.
