With Qt 5.11 at least, RtL text will be drawn RtL even when the
(undocumented) flag Qt::TextForceLeftToRight is applied to the
QTextLayout object. This creates selection issues for Hebrew text
marked as English.
The solution is to do the same as in breakAt_helper, that is prepend
the string with a direction override unicode character.
Doing this requires to introduce a TEXTLAYOUT_OFFSET constant that has
to be used wisely to account for this extra character.
Fixes bug #11284.

As of LaTeX2e 2018, characters are made active earlier, which results
in new expansion problems.
Following a suggestion of Markus Kohm (pc) and the TL mailing list [1],
we embrace non-ASCII input paths in \detokenize. This relies on e-tex,
but I think we can assume this is nowadays available everywhere.

This is a fixup to 4ecbff00. When a file is loaded and the cursor is
set, it is required to first compute metrics to be able to scroll the
screen correctly.

When using QTextDocument to check the natutal size of a text, one has
to remove the text margin, which is not useful here.

Add the "hyperref-driver=dvips" option to the extra flags of the
latex->dvi converter so that the breakurl package is automatically
loaded when needed.

Instead of "Save" (permanently) and "Apply" (temporarily), OK and Apply
now always save permanently, unless the new checkbox "Apply to current
session only" is checked.

If we were not ready to paint the screen, this does not mean that we
should give up on repainting, just potpone it.
I thought that it was bad to call update() in the paint event, but I
cannot find reference to this anymore and everything seems to work as
intended.
Fixes part of bug #11323.

When a raster image with an advertised pixel density different
from 72 dpi is included in a latex file, the output image dimensions
are scaled by the ratio 72/pixel_density. Hence, if a clipping
bounding box is specified, it has to be scaled by the same ratio,
otherwise the images will be clipped differently on screen and output.
Here we use the extractbb command (present in any TeX distribution)
to ask about the output dimensions of the image as dictated by the
pixel density and compute the scaling ratio by the knowledge of the
actual dimensions. If, for whatever reason, extractbb is not found,
everything goes as before, because the clipping bounding box will
simply not be corrected.

On Windows, start viewers in detached processes in order to avoid
a crash of the QProcess destructor when their thread terminates.
The opening of a console window is avoided by redirecting to the
null device all standard I/O channels.
This can happen when the inset that contains the cursor is outside of
the screen.
THis is only a workaround. The real solution would be a
processUpdateFlags(FitCursor) call, but the code is not ready for that
yet.
Fixes bug #11296.

We do not know what to do with horizontal scrolling events, so we ignore them.
Note that the code has to be different between Qt4 and Qt5.
