We need to lowercase the language again (it's \begin{Arabic},
but \textarabic)

This assures that they are output as straight quotations marks (e.g.,
babel shorthands).
Fixes: #75 [sic!]

This requires moving the bool that tracks this somewhere that it
is visible from BufferView. It seemed to make sense to put it as
a static member of InsetCitation.

But use default "true" to maintain current behavior if not explicitly
stated otherwise.

In cursorY, it is dangerous to access par_petrics_[0], since one does
not know whether metrics have been computed for this paragraph (which
may be off-screen).
It is safer to use parMetrics(0), that will compute the paragraph
metrics as needed.
Fixes bug #8120.

This is a follow-up to 758de957.
- unify the metrics and drawing of \sqrt and \root using helper
functions mathed_root_metrics and mathed_draw_root.
- compute the vertical spacing above the nucleus of the root following
rule 11 of the TeXbook. In particular, it is different in inline and
display style.
- draw the root glyph without hard-coded pixel values. Make the line
width depend on the zoom.
more work is needed to implement properly rule 11:
- Ideally, we should use sqrt glyphs from the math fonts. Note that
then we would get rule thickness from there.
- The positioning of the root MathData is arbitrary. It should
follow the definition of \root...\of... in The Texbook in
Apprendix B page 360.

Now the helper class contains logic that checks whether buffer are
known before closing them. This avoids potential crashes.
Use it in different places to siplify code. It is not clear at this
point whether it should be used everywhere.
Followup to bug #10847.

The correct behavior is to go to position 0 going up from first row,
and to end of row when going down on last row.
The targetx value of the cursor is not updated, which makes cursor
movement more natural.
Fixes bug #10701.
