Until now the regeneration process was starting as soon as the zoom scale
factor was changed. This was causing some glitches, especially if the zoom
was changed by the mouse wheel, as on each change the process was started
again and again making zoom changes painful and causing races such that
one could end up with the text at some zoom factor and the previews at
another one. After this commit, the regeneration is started only after
the zoom factor has been stable for about 1 second. In this way, one can
use the mouse wheel for changing back and forth the zoom factor at own's
heart desire without any slow down due to the regeneration process running
in the background. For those using previews with numbered math equations,
a nice possibility for getting the equations correctly numbered in sequence
(after removing or adding an equation) is using the shortcuts Alt+ and Alt-
in rapid sequence (less than a second between the keystrokes). Previously,
this would have triggered twice the regeneration, but now only once.
This is an amendment to 0e2ea9d4, so no status line is needed.
The patch also makes sure that only the macros actually used in a
math inset are included in the preview snippet. In this way, the
size of the tex file used for generating the previews does not
explode in the presence of lots of macros.
As JMarc notes on the ML, the referenced commit modifies a full
buffer just in the middle of a dispatch action.
Further, this commit lead to an assertion [1], although it is not
clear to me whether the root cause of the assertion is the commit
that is being reverted here, or one of the issues we have with
previews and macros.
This reverts commit 6ac04e21f4.

Revert "layouttranslations: Arabic update by Hatim"
This reverts commit 407d5bf228.
It is not permitted to change lib/layoutranslations during a stable cycle.
The reason we want to do this is for if there is pasting across buffers.
For within buffer, the previews should already be updated. Calling the
buffer-wide updatePreviews() might seem like overkill, but actually it
should be quick because only the previews that need updating are updated
(and this check feels quick to me, although I did not profile).
If we were to loop through the pasted text and update each preview
individually, this might take more time. When updating previews
together, only one .tex file is compiled.
(cherry picked from commit 73460423ad)
Clarify that a user-defined external_templates file would replace
the library version. For more information on this issue, see #3983.
(cherry picked from commit 1d28d90801)
This is a collection of changes to the python scripts in master made
for trying to sort out the mess that had accumulated about previews.
After this audit, it turns out that bugs #6369, #9354, #9508, and #9510
are now fixed. If pdftocairo and epstopdf are vailable, it also makes
the conversion performed by the legacy conversion paths much faster
and improves the quality of the generated bitmaps.
Create new helper class UndoGroupHelper, which simplifies a lot the
handling of undo groups in cases like this one. The class tracks open
undo buffers and allows to switch buffers transparently.
Using the class for advanced search and replace is trivial. The class
may be useful in some other classes.
Also fix the status.21x file that had DOS end of lines and reorder a few undo-related entries.
Fixes ticket #8658
The recipe for reproducing this crash is to do a search and replace
that changes a string present in a collapsed inset, and then undo.
This is a followup to d5eeabcf, which used editable() instead of
isActive(); this commit was amended at a6bc4a2a, since editable() is
not set properly in mathed.
Truth is, editable() is not the right property to test against, since
it is false for a collapsed inset, which does not prevent a cursor
from pointing inside. Therefore sanitize should not change the cursor
in this case.
Hopefuly, this is the last word on the subject. Alternative would be
to drop this if()-clause completely.
