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.
Fixes bug #11377.

When using QTextDocument to check the natutal size of a text, one has
to remove the text margin, which is not useful here.
Fixes bug #11353.

Do not use LTR environment (bidi) at all, since it adds unwanted
paragraph breaks.

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.

(cherry picked from commit 2617a4dd501c64048573e2d9c4e6fb9f423a1067)
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.
