Since be836909c5 the positioning of super- and subscripts
for symbol fonts has been broken because the metrics of the
font of the environment (rather than those of the symbol itself)
were used.
When running redoParagraph, it may happen that the ascent of the first
row changes. Since the ParagraphMetrics position is actually the
baseline of its first row, it may be necessary to update it.
Fixes bug #11601.

This is a fixup to commit 611df441. It seems that the wrong unicode
property was selected. It could be that both classes should be used.
Fixes bug #11900.

This commit adds the mathed command \mathds that selects a
font more appropriate than \mathbb for typesetting the
mathematical symbols for the natural (N), whole numbers (Z),
rational numbers (Q), real numbers (R), complex numbers (C),
and some others.
As in the \mathbb case, only capital letters are supported,
but in addition one can also typeset a symbol often used for
representing the indicator function (\mathds{1}) and the
letters a, h, k.
Fixes bug #11887.
The above mentionned patch did paint the background of the sublabel to
avoid "bold-like" effect. However the correct backgound color is the
row's one, not the inset's one.
To fix this, extend MetricsInfo::backgroundColor to work when no inset
is specified. The code is also simplified as in master.

note-next and reference-next should trigger an update so that metrics
are updated when the cursor ends up in an auto-open inset.
Fixes bug #11870.

The binding <Alt + p, Shift + Return> is already used for
environment-split outer, so we bind <Alt + p, Alt + Return>
to environment-split before.

Before, we would continually set the selection to the empty string,
to maintain ownership. This causes problems with clipboard managers
GPaste and CopyQ. Further, in theory this should have better
performance since checking ownership should be faster than setting.
A disadvantage of this change is that the timestamp of the selection
will be old at this point in the code. However, when the selection
is requested, we put the selection contents at that point so the
selection timestamp should be accurate then. Further, the selection
contents are not accurate at this point in the code (they are just
the empty string), so it is not clear whether having an accurate
timestamp is beneficial.
Fixes#11715.

This was already done for gcc9 and saves tons of warnings.
Note that the warning in Qt are gone with Qt5.13, so eventually we
will have to get rid of our own copy issues.

There are two techniques that I know of for forcing the direction of a
string, regardlessly of whether its contents is naturally LtR, RtL or
undecided.
1/ The unicode LTR/LTR override characters. This is supposed to be the
clean way, however, it does not seem to work with Qt 5.14 (see
#11691).
2/ The undocumented QTextLayout::setFlags method. This is used
internally and allows to pass the (undocumented) flags
Qt::TextForceRightToLeft and Qt::TextForceLeftToRight. This was
used until we had issues with Qt 5.11 (see #11284).
In order to get the best of both worlds, this patch allows to enable
those two methods separately, and actually enables both at the same
time by default!
Fixes bug #11691.

As a consequence of fix e64ea357 to ticket #10797, we draw a bit too
much of the inset background outside of the inset (visible for insets
with colored background). #10797 is a ticket that triggers when the
cursor has a width larger than 1.
This patch limits the problems in two respects
* nothing is done on the left, since the cursor width only expands on
the right.
* on the right, the extra width is limited to cursor width.
Fixes bug #11786.

Move cursor at beginning of selection after deletion. Else backspace
operation gets stuck in a loop (tries to remove the selection again
and again).
This also fixes backspace deletion of insets with confirmDeletion() == true.

If the file of an InsetInclude does not exist, loadIfNeeded will try
again and again to look for it. This is very bad for files with many
include insets, especially on windows.

This is better than making sure that the inset has exactly one cell.
In the future, inset-dissolve could be extended to dissolve all the
cells contents in the enclosing text.
Note that this check does not appear in mathed, and using dissolve in
e.g. fraction inset may lead to data loss (only current cell contents
is preserved).

This patch is not ready yet. Moreover, change the assertion in
InsetMathGrid::colAlign to a simple test.
As a consequence, math split inset might show a bad alignment in some
situations.
This reverts commit d3fd915662.
Like with macOS, the Wayland compositor seems to require a
backingstore when doing partial updates like we do.
This extends the mechanism that has been introduced for macOS. This
has to be done at run time, not compile time.
Fixes bug #11692.
