Also output the right one depending on whether the unit is "mu" or
not. Indeed, the two macros are identical, except that \mkern only
accepts unit mu, and kern does not accept it.
With this patch, both macros accept all units, but on writing beck,
the right one is used.
It may happen (for example with on the fly spell checking) that
GuiFontMetrics::pos2x is called with a negative pos value. Add a
special case for this situation.
Fixes bug #10506
This helper method is used to set the inset dimension cache at metrics
time. However this is already done by the metrics code itself
(MathRow::metrics, TextMetrics::redoParagraph), so that there is no
need to do this same work again in a different place.
Also, InsetPhantom::metrics is removed, since it does not do anything
interesting.
This commit comes with a mild risk attached (it might be that some of
these calls were useful after all!), but all of this is fixable.
This helper method is used to set the inset position cache at drawing
time. However this is already done by the drawing code itself
(MathRow::draw, RowPainter::paintInset), so that there is no need to
do this same work again in a different place.
Note that the inset positions are still set in InsetTabular::draw for
each cell.

This encoding (modified Mac Cyrillic for Asian languages) is rarely used and not supported by Gnu iconv.
Update comments in lib/encodings.
Update ctests: Gnu iconv only supports cp858, if configured with "--enable-extra-encodings".
Up to now Inset::dimension was either a helper function to access
CoordCache, or... something else. This created problems to properly
use it.
In particular, the definition of InsetText::dimension created problems
for child classes. Removing this definition (actually renaming it to
dimensionHelper) allows to streamline the code.
* endInsertRow was incorrectly placed before endResetModel, sometimes leading to
bad access by the view before it was informed that the model was empty. In
fact begin/endInsertRows were redundant with begin/endResetModel.
* Empty blocks are not supposed to be shown. This happened when moving the
cursor. A valid block is now selected intead. Due to the design/optimisation
of the model update, this requires a first update with an empty
model. Simplify the old code.
Tweak the algorithm so that a BOX math row element can have some
spacing. To this end, MathRow::before/after do not look at the type of
an element for deciding when to skip it, but rather to its math class.
In the new setting, the spacing algorithm works on all elements, but
skips the MC_UNKNOWN elements as if they were not present. As a
consequence, the two element types BEGIN and END have been replaced by
a single DUMMY (they can be recognized from their class).
To simply the code, add a new `mclass' argument to the
MathRow::Element constructor (default is MC_UNKNOWN).
Macro nesting is now recorded into the macro inset itself. This allows
the ArgumentProxy inset to determine whether it is editable or not by
looking at its macro.
Remove code in the metrics and draw methods of ArgumentProxy: this
code is AFAICS not active anymore, since arguments are linearized into
math rows.
Use Changer idiom to change locally the values of MecticsInfo::base.macro_nesting.
This is a long standing issue, present since the new math macros
inception in version 1.6. It manifests as a display issue when a
macro with optional arguments appears in the optional argument of
another macro. In this case the display is messed up and it is
difficult, if not impossible, changing the arguments as they do not
appear on screen as related to a specific macro instance. It also
manifests as latex errors when compiling, even if the latex output
is formally correct, due to limitations of the xargs package used
to output the macros. Most probably, both aspects have the same
root cause, as simply enclosing in braces the macro and its
parameters solves both issues. However, when reloading a document,
lyx strips the outer braces enclosing a macro argument, thus
frustrating this possible workaround.
This commit solves the display issue by correctly accounting for
macros with optional arguments nested in the argument of another
macro, and circumvents the xargs package limitations causing errors
by enclosing in braces the macros with optional arguments appearing
in the argument of an outer macro when they are output. This means
that when loading an old document with such macros and saving it
again, the macro representation is updated and will have these
additional braces. However, as such braces are stripped by lyx on
loading, there is no risk that they accumulate.

The missing character problem is fixed upstream.
Also fix the scaling of the \sun-symbol-index by wrapping the symbol in \text.
(wasysym's \sun is valid in text and math mode. LyX currently adds a spurious \ensuremath.)
As Enrico pointed out in http://www.mail-archive.com/lyx-devel@lists.lyx.org/msg131411.html, the loading error of testcases_speed.lyx is caused by tags from a LyX development version that were later removed but never handled in lyx2lyx.
LaTeX export still fails with
! Argument of \xargs@grab@opt has an extra }.
These tests are "unreliable" and thus their export status contains
less information than reliable tests. However, it contains some
information and could still be used to find regressions. This commit
helps keep the output of a vanilla "ctest" command clean.
