This fixes an error in the preview generation with polyglossia
and bidi that prevents snippet generation (and consequently also
"math as image" xhtml output).
Fixes: #10716.
* Provide for vector fonts only if needed.
* Make sure microtype doesn't throw a trantum in dvi mode.
* Use correct macro definition in preview insets.
Was forgetting this last bit from 64e0c558. Also give a message such
that the user is informed that not everything is lost if latex fails.
With this, the previews are generated also when the document directly
specifies a specific pdf output format.
This is a followup commit to 691fdea3 and restores the behavior of the
script as it was intended before 64e0c558, other than taking into account
possible inclusion of files that only pdflatex can process and the
possibility of multiple defined math macros.
The instant previews in the math manual now work again.
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.
Fedora ships these chmod 644 and has never seen a problem. The advantage
to doing this is that it better controls what version of python we are
using to launch the script, and it will reveal if we're somehow somewhere
not controlling that properly.
Let's have this in trunk for testing. The real difference maker
when it comes to color is whether we use dvipng or ghostscript.
For dvipng:
- The color info is passed as command-line arguments.
- The tightpage option is not necessary, and since it adds
ps specials to the output, we shouldn't use it.
For ghostscript:
- The color info needs to be in the latex file.
- The foreground color is set for each preview inset.
- The background color is set by \pagecolor in the preamble,
which is understood by pdflatex, but ignored in dvips mode.
Thus dvips is handled with a ps special.
- The tightpage option is necessary to crop the images.

- Break up steps 1, 2 and 3 from the legacy preview mechanism.
These are really separate steps.
1) Add color info, run latex
2) Run dvips
3) Run ghostscript
- In the case of pdf output, skip step 2 and go directly to step 3.
- Make sure that we fall back to the legacy conversion whenever we can.

Introduce --debug and --verbose flags to control output. Also, use the
python subprocess module to capture stderr from external commands, thus
bumping the python requirement to version 2.4 or later.

Move some common variables to lyxpreview_tools. Otherwise,
add a few variable names, making it easier to track things.

Whitespace and line endings only, in preparation for some serious work.

when latex fails with a preview. Fixes bug #7303 (IP fails with hyperref).
Patch by Ale with suggestions from Enrico

* src/PreviewLoader.cpp:
- add conditions for preview with pdf output
* lib/scripts/legacy_lyxpreview2ppm.py:
- if no dvi preview file is available, check for a PDF file
and process that, if found
- also produce png output, if requested.
* lib/scripts/lyxpreview2bitmap.py:
- if no dvi preview file is available, check for a PDF file
and process that, if found
* lib/scripts/lyxpreview_tools.py:
- move some common functions here

* src/support/os.[Ch]
(python): new function, return the python command
* lib/lyx2lyx/lyx_1_5.py
(revert_font_settings): replace tabs with spaces
The rest is simply s/python/python -tt/ and
s/"python"/lyx::support::os::python()/ where appropriate.

Implementation is as similar as possible to the well-tested code in the
1.3.x tree.
