This is indeed a good argument in favour of cloning the Buffer.
Nope. I just profiled with sysprof what happens when
typing in UserGuide with LaTeX source shown (with full
source). Conclusions are
* it is painfully slow :)
* 69% of time is spent in libQtGui itself
* 4.3% of time is used to generate the full source code
I guess that qtextedit does not like big texts...
Maybe, it's because of the syntax-markup. It has to parse the whole tex
'file' to get the coloring right ?
I just tried without it and it still is slow. So the real bottleneck
seems to be QTextDocument indeed. But as I said, we do a full reload at
each keystroke...
