Showing deleted display math by enabling "Show Changes in Output" was
only possible with dvi (through dvipost). Although LyX strikes out
such formulas on screen, it was impossible obtaining an output
directly using pdflatex (or other engines producing pdf) because
ulem cannot cope with display math material and gives errors.
The solution is to strike out by ourselves such deleted formulas.
I took into account several options. One of them would produce
an output similar to dvipost (which strikes out each element), but
would have required much more changes in the output routines.
Eventually, I opted for using tikz, which gives a more clean
output (as it requires to simply adding a preamble and a postamble
to the latex code of any displayed math, instead of a mark up
tailored to each particular math construct). The look of the pdf
output is similar to the way LyX strikes out the equations on screen.
Replace the manual manipulation of a stack of RowEntries with a Changer
function. When I introduced the stack of RowEntries, I did not know about the
Changer mechanism.
WriteStream is now built from an otexstream instead of an odocstream, and
therefore counts lines in a TexRow. Calls to TexRow are added in relevant places
in math insets.
This finishes adding line tracking for math in the source panel and for forward
search.
output routines. The idea is that in some cases people may not want to
use MathML, so we are going to try to give options.

* MathStream{.cpp, h}:
- replace bool dryrun() by enum output that also knows whether the stream is for instant preview
* InsetMathHull.cpp:
- tell the stream whether we use it for instant preview.
* MathString.cpp (write):
- gracefully catch encoding exception for instant preview.

6047: Lyx 1.6.3 unable to typeset the third chemical equation of the
file mhchem.lyx (package mhchem)
4043: mhchem support
5394: support for the mhchems's \ce command
The \ce and \cf insets are text mode environments that allow entering
spaces and mathmode commands. LyX leaves them alone and doesn't try to
be smart, i.e., the behaviour is exactly the same we had in the old days
with text-in-math mode environments, before the introduction of the
\ensuremath and \lyxmathsym macros. This means that in those environments
one has to know what he is doing, as LyX will not offer any protection.
The hack of enclosing \ce and \cf in a \text{} environment in order to
be able to enter spaces is no longer necessary.

* src/mathed/*.cpp:
- Track mode (math or text) when outputting latex code and
properly wrap commands that are in the wrong mode with
either \ensuremath or \lyxmathsym.
* src/mathed/MathParser.cpp:
- Parse \ensuremath and \lyxmathsym, such that exported latex
produces the same result when imported back.
- Replace latex commands with corresponding unicode symbols.
* src/Encoding.cpp:
- Implement Encodings::fromLaTeXCommand() for converting either
a single or a sequence of latex commands to unicode symbols.

inside math mode, and also ensure the proper mode inside math when using
the symbols from the unicodesymbols file. This hopefully fixes bug 3938.
Note that this approach could also be used for fixing bug 1527.
