For a displayed equation, the height is artificially increased by a displayMargin() in InsetMathHull::metrics if it is a displayed equation and there is a preview.
This extra height is not covered by the preview image and what one can see is the background as drawn by the MathHull inset. The color of this background should be either Color_mathbg or Color_background depending on whether the preview is shown or not.

Now we also 'support' \xymatrix!C (columns), \xymatrix!R (rows), \xymatrix!0 (all equal and ignore entry sizes) and \xymatrix! (all equal).

as to allow us to call the routine when we are preparing for output and
so to do certain things we might not want to do every time.
This is an abuse of updateLabels(), in a way, but updateLabels() long
ago became the general recurse-through-the-Buffer routine, and to
implement the sort of thing I want to do here in validate(), say, much
of the code in updateLabels()---in particular, the counter-update
code---would have to be duplicated. So I believe this is the best, and
easiest, way to go.
Actual use of the new argument will follow.

The fix consists in not updating the macro while it is being edited,
and this is accomplished by the changes in MathData::updateMacros().
However, when clicking away with the mouse I was getting another crash,
which is cured by the changes in MathMacro::notifyCursorLeaves().

The enum is overkill for now, but will be useful if anyone decides
really to return to this stuff. It's apparent that there are some
powerful tools here---like the ability to pipe expressions through
Mathematica.

The fileformat change is also needed because of our mistake that we load mhchem since LyX 1.6.4 automatically so that files created with LyX 1.6.4 won't compile under LyX 1.6.3. Now at least all files created or opened with LyX 1.7 can be reverted to the fileformat of LyX 1.6.x and can therefore be read by all LyX 1.6.x versions.

This patch initializes the buffer_ member of a MathHull inset in most
(but not all) cases. The problems with buffer_ should be greatly
allievated now, but there still can be some corner case.

This is another ad-hoc solution for the problem of a zero buffer pointer while reading a document or when using cut&paste.
This simple solution would be suitable for branch.

When pasting "# a" within \mbox{} through Ctrl+Shift+V, the space is

This reverts part of r10553. There, an extra '//' was added when the last line was empty. However, this really makes an extra line and that is visible when the lines have a line number. The bug #2067 that would have been fixed by this does not seem to 'exist' anymore.

In order to fix#6047, I needed a further mode other than MATH_MODE
and TEXT_MODE. In this mode, LyX should have behaved as in TEXT_MODE
but should also have allowed math mode commands. Well, this mode was
already implemented in LyX as UNDECIDED_MODE. Currently, this mode is
used nowhere except in the strange case where a math hull is not
present. It cannot be created by any other mean than editing a .lyx
file and getting rid of the $...$ math delimiters. This kind of
file can be reloaded in LyX and you would see a strange math formula
in text mode outside of mathed. Of course, trying to latex this file
would cause errors. After this commit, this strange mode is still
possible, but now all math insets correctly declare that their mode
is math mode (instead of undecided, and unless they state otherwise)
and bugs such as #6049 are fixed.

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.
