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.
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).

* 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.
