0751f96d25 Properly account for font size when generating previews
Patch by Guillaume.

dd09a5cabc Use the draft option for microtype
Instead of redefining \usepackage for avoiding the microtype package
when generating previews in dvi mode, the draft option can be used
for disabling it. This also allows to somewhat simplify the
fix_latex_file function.

98a5072a58 Fix a couple of issues with macros and previews
* Fix typo causing to only account for the first char of a macro name
* Also check for macros as arguments of other macros

11c2b7792c Replacement for commits bc47054b and ad0d0f6d
The strategy adopted in bc47054b had some drawbacks related to the way
instant preview snippets are generated. See the subthread starting at
http://www.mail-archive.com/lyx-devel@lists.lyx.org/msg187916.html
for details.

The strategy adopted in this commit is that of adding macro definitions
only for the macros actually used in a preview snippet, independently
of whether some macro was already used in a previous snippet. In this way
the snippets don't need to be changed according to whether they are
compiled as a whole or separately from each other. This fact was causing
the regeneration of a preview snippet whenever the cursor entered the
corresponding inset, even if the generated image would have not changed.
The problem of defining or redefining a macro is taken care by the
python scripts.

5998555743 Account for the trailing optional argument of \usepackage.
The full syntax is \usepackage[<options>]{<name>}[<min.date>]
even if this is not documented in my old Lamport's LaTeX book...

07169c7be2 Report how many preview snippets fail.
Instead of warning about latex problems that, most probably, are worked
around by the script, report how many preview snippets were not produced.

3924030e82 Fix some preview issues reported on the devel list.
* 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.

bc47054be8 Properly fix
Avoid that \newcommand[x] definitions of math macros are pushed multiple
times to the preview loader.

Redefinitions (via \renewcommand[x]) are properly handled.

2bbf775c74 Detect hyperref when generating previews
If use of hyperref is detected, the postscript route is not attempted
(because we know it will fail) and the PDF route is directly chosen.
Also account for all upper case extensions for pdflatex image files.

d44b0a19cb Amend 75f7eafd
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.

75f7eafd65 Try even harder to obtain an instant preview
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.

691fdea346 Try hard to obtain an instant preview.
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.

f9de88c53c Remove the shebang line from our python scripts, per Jose's suggestion.
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.

35b580fb30 lyxpreview: Simplify the color handling.
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.

45280f6bb5 Refine the lyxpreview legacy conversion (the ghostscript one).
- 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.

10868c31ac Merge the preview mechanism for lilypond-book with the standard one.
- Handle the preprocessing in the main lyxpreview script with the
    command-line arguments --lilypond and --lilypond-book=exe.
  - Remove the obsoleted file lyxpreview-lytex2bitmap.py and the
    corresponding lines in configure.py.

Fix for the japanese preview still to come.

2bd747fad4 Add command-line arguments to lyxpreview2bitmap.py
Add command-line arguments in a standard unix fashion, using getopt.

    Usage: ./lyxpreview2bitmap.py <options> <input file>

    Options:
      -h, --help:    Show this help screen and exit
      --dpi=<res>:   Resolution per inch (default: 128)
      --png, --ppm:  Select the output format (default: png)
      --fg=<color>:  Foreground color (default: black, ie '000000')
      --bg=<color>:  Background color (default: white, ie 'ffffff')
      --latex=<exe>: Specify the executable for latex (default: latex)

    The colors are hexadecimal strings, eg 'faf0e6'.

The changes to PreviewLoader.cpp break the preview of lilypond-book
and japanese files, but they will be handled in the next commits.
