Given that TexMaths is configurable and lets the user change the path to
the latex binary, I guess one option would be to ship latex within the
snap. That might not be very user-friendly, as I'm not convinced the
extension would find it without the user telling it where to look for
it. And we need to check how much bigger the resulting snap would be
with a latex installation.
As the extension is multi-platform, I guess shipping latex within the
extension itself is not really an option.

Title:
[snap] permission restriction on /usr breaks TexMaths extension
Status in libreoffice package in Ubuntu:
Confirmed
Bug description:
I am the developer of a LibreOffice extension (the TexMaths equation
editor) and I got reports of users who can’t use this extension with
the snap version of LibreOffice, because of permission restrictions on
/usr (the TexMaths extension, and probably others, use external
programs located in /usr/bin).
Indeed, the TexMaths extension uses external programs like
/usr/bin/latex, /usr/bin/dvipng, /usr/bin/dvisvgm and the texlive
LaTeX packages to produce LaTeX equations in LibreOffice (in Writer,
Draw and Impress components). Since the access to /usr from the snap
packages is not possible, this breaks TexMaths.
I guess there are other extensions that could be affected by this
problem.
I tested and reproduced the issue in Ubuntu 16.04.3 LTS (64 bits) with
the snap package of LibreOffice 5.4.4.2.
Here is a link to download and test TexMaths (please note that texlive
must be installed before) : http://roland65.free.fr/texmaths/
