[Request] Syntax highlights for LaTeX math expressions in Markdown

[thunderbird-1990]

At the moment, PaperColor does not provide syntax highlight for LaTeX math expressions inside (e.g., Pandoc-style) Markdown files.

I am aware that some plugins (e.g., vim-pandoc-syntax, vim-markdown) can achieve this, but my experience is that PaperColor looks better (e.g., see this issue or this issue on why the two plugins above don't look as nice as PaperColor).

At the moment, I use vim-SyntaxRange so that Vim treats math expressions inside Markdown files as LaTeX "environments", something like this:

autocmd BufReadPost *.md call SyntaxRange#IncludeEx('start="\\\@<!\$" end="\$" skip="\\\$"', 'tex') | call SyntaxRange#IncludeEx('start="\\\@<!\$\$" end="\$\$" skip="\\\$"', 'tex')

I am wondering whether this can be implemented in PaperColor. According to this, Vim-markdown does something similar and treats math expressions as LaTeX environments.
