Preserve numbering of previewed math formulas on zoom
The preview snippets are cached in a seemingly random order, such
that, when regenerating them on zoom, the math previews would be
numbered accordingly. Hence, we have to go through the insets to
get the correct order. This is a bit slower but unavoidable.
- enrich the examples
- add info about naming
- formatting fixes to improve the layout of the PDF
- make the document compilable also if the package insdljs is not installed
Use pdftocairo (if available) for instant preview.
If pdftocairo is detected, it is used for generating bitmaps in the
legacy method route in preference to ghostscript. This is justified
by the fact that the conversion is 4 to 5 times faster and the
quality of the generated images is superior.
When the dvipng route is selected and latex fails, the lyxpreview2bitmap.py
script simply bails out. The failure may be due to using a specific pdf
only feature in ERT (for example, the inclusion of a pdf image).
In this case the procedure may succeed simply trying to use pdflatex
and the legacy conversion method.

Update previews when going to a bookmark (#6173)
Note that I move the definition of cur up because we need to check if
it changed before the return. I also removed the const because
notifyCursorLeavesOrEnters() requires that.
This commit probably fixes other issues for any inset that defines
notifyCursorLeaves().

Update previews after pasting (#6211)
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.

Update previews on preference change (#9507)
Normally the theBufferList().updatePreviews(); statement would go inside
of PrefDisplay::applyRC. However, that would not work well because
Buffer::updatePreviews() calls loader() which conditions on
(lyxrc.preview == LyXRC::PREVIEW_OFF) but the new RC has not been set at
this point.

Preview and math now update on screen-up (#6173)
When editing a preview inset, or math, when we leave the inset, we
should update the preview. This update now happens for screen-up and
screen-down (commonly bound to Page Up and Page Down).
Note that this is only relevant if preview is turned on in
preferences.
This commit probably fixes other issues for any inset that defines
notifyCursorLeaves().

ctests: remove some tests from ignored file
The bug that caused these tests to enter into infinite loops
(and have a memory leak) has been fixed. These tests now
pass on an updated TeX Live 2014 as well as the current TeX
Live 2015 pretest.
The \lightning symbol is text mode only. Hence, for using it in
mathed, it must be inserted in a text mode environment such as
\mbox, \text, etc. However, as it is not marked as textmode,
LyX "helpfully" encloses it in \ensuremath everytime one tries
to put it in a text mode environment, thus defying the countermeasure.
By declaring it textmode only, LyX stops doing that and thus it can be
correctly output by simply selecting it and hitting Ctrl-M.
Adapt creation of preview images to the defaul document output.
Sometimes, even compilable documents could not display preview
snippets. Previously the preview was computed only with help
of latex or xelatex.
This also fixes #9371

Fix tex2lyx linker error on windows
The FontMetrics dummy class was in the wrong namespace. Linking on linux
did work because the GNU linker is more clever than the MSVC linker for this
particular example and throws out more unused code, so that theFontMetrics was
not referenced at all.

ctests: disable two fr/Math.lyx tests
One of the tests is also disabled for es/Math.lyx. However,
the other test passes for es/Math.lyx. To reproduce,
open fr/Math.lyx, click "Use non-TeX fonts", and choose
e.g. "FreeSans" for the three fonts. Then view as PDF (LuaTeX).

Implement and bind buffer-move-{next,previous}
Control + Shift + PgDn now moves a tab to the right.
Control + Shift + PgUp now moves a tab to the left.
These keybindings are consistent with Chromium, Firefox,
Nautilus, and gnome-terminal.
Note that I allow for wrapping. This is consistent with
allowing wrapping for buffer-{next,previous}, but there
might be reasons to disable it in the future.

Fix compilation of the template ACM-sigplan.lyx
This template was only reported as failing to compile by LyX as of 0a6120cb. I do not know how long this template was actually failing
to compile without error. The problem was that the class requires
\doi to be defined. This might not have been a requirement in
previous versions of the class.
Thanks to Enrico for finding the problem and solution.

Add getStatus check that >1 tab for switching
buffer-next and buffer-previous are now only enabled
if there is more than one tab. Note that it does not
matter whether we are at the first or last tab because
we cycle.
Do not close LyX in the commitData process (#9277)
Since the logout process still can be canceled here, we should only
check that all dirty buffers are saved and that the session state is
recorded.
Please test, particularly on Windows and OSX, that logging out with LyX
running (both with and without dirty buffers) proceeds sensibly and that
the LyX session is correctly restored when you re-login.
Prevent crash when attempting to restore a file multiple times.
We currently cannot restore multiple views of the same buffer properly.
On the mac, we even crash.
So do not try it, record each file only once in the last opened list.
