The code was checking only for particular vertical alignment requests
in order to decide to nest a standard array into a 1x1 ams matrix.
However, also vertical lines are not possible in ams matrices.
These uses are inefficient (a loop really) and require that pit_type
is ptrdiff_t.
Instead, RandomAccesslist::constIterator is renamed to iterator_at and
a version adding a non-const iterator is added. Additionally, the
method retirns end() when position is equal to the size of the
container (see #11861).
lyx::next and lyx::prev are removed, and std::prev is used in the few
places where the code requires it (for no good reason IMO).
Starts to be crazy. Many fonts have to be (visually!) inspected, because there is
no hint about this feature.
Also, for many fonts it is a senseless information.
We need a third value (besides serif and sans-serif)

Added (de)selecting fonts through its capability (latn, math, arab, etc)
Recognize also trebuchet in font name as sans-serif font
Recognize also fixed in font name as monospaced font
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.
