Paul Menzel 68e333e0bd teximg: Use `\[` and `\]` instead of not recommended `$$`.
It is not recommended to use the double dollar symbol `$$` to set displayed math [1][2].

Paul Menzel 7415aee9cc teximg: Use Unicode UTF-8 encoding by default.
If I am not mistaking all source files in ikiwiki are encoded in Unicode UTF-8.
Adding `\usepackage[utf8]{inputenc}` enables LaTeX to deal with the encoding.
As a consequence some special characters like umlauts can be used in the source
code which is useful for foreign languages.

        [[!teximg code="a = b \text{ für alle } b \neq 2"]]

But for example »≠« cannot be used in LaTeX right now. One has to use other TeX
systems like XeTeX or LuaTeX featuring native UTF-8 support or use additional
nonstandard packages like uniinput [1].

I used the package `inputenc` (`texdoc inputenc`) and not `inputenx` (`texdoc
inputenx`), because I have not used `inputenx` that much and using the option
`math` is not supported in Debian (and I guess other distributions too) since
`inpmath` is not included in CTAN.

Joey Hess 6d27bbd026 Fix utf8 issues in calls to md5_hex.
This prevented comments containing some utf-8, including euro sign, from
being submitted. Since md5_hex is a C implementation, the string has to be
converted from perl's internal encoding to utf-8 when it is called. Some
utf-8 happened to work before, apparently by accident.

Note that this will change the checksums returned.

unique_comment_location is only used when posting comments, so the checksum
does not need to be stable there.

I only changed page_to_id for completeness; it is passed a comment page
name, and they can currently never contain utf-8.

In teximg, the bug could perhaps be triggered if the tex source contained
utf-8. If that happens, the checksum will change, and some extra work might
be performed on upgrade to rebuild the image.

Josh Triplett 9f75d3b1f3 teximg: Make TeX handle preventing unsafe things; remove insufficient blacklist
TeX has configuration options that prevent unsafe things like shell
escapes and insecure file reads/writes.  Turn all of them on.

teximg's regex-based blacklist does not suffice.  For instance:

[[!teximg code="""
\catcode`\%=0
%input{/etc/passwd}
"""]]

Remove the blacklist, since the TeX configuration options seal off the
underlying mechanisms more safely, and the blacklist blocks other TeX
commands that can prove useful.

Joey Hess 69e35d3c51 willu's teximg changes
* teximg: The prefix is configurable, and has changed to not include the
  nonstandard mhchem by default. (willu)
* teximg: dvipng is used if available to render images. Its output is
  antialiased and better than dvips. If not available, the old dvips+convert
  chain will be used. (willu)
* Drop suggests on texlive-science, add suggests on dvipng.

Joey Hess cb8d1c8642 revert destpage part of f7bdc2385
destpage does not normally need to be worried about when creating other files
as part of the process of rendering a page. Using destpage results in
inlined pages creating two copies of such files. It works to not use destpage
in this case because the inlining page depends on the source page, so if the
source page is modified or deleted the inlining page will be updated.

Joey Hess f7bdc2385d * Use forcebaseurl to make page previews be displayed with the html base
set to the destination page. This avoids need for hacks to munge the urls
  in preview mode, which fixes several bugs.
* Several destpage fixes in plugins.

Patrick Winnertz 81c726982b I've wrote a little patch for the bug in teximg (can only include fomula on
one page).
