Referenced relative files not resolved

[dougrich]

Since the latex is compiled inside a temporary directory, latex commands that reference relative files are not resolved. Examples are include and input.

@dougrich — long delay, but spawn + latex might be a better fit. I believe most of the reason for this module to exist is to avoid gobs of input and output files so that you can go right from a string to pdf data, for example, without feeling like you're hitting the filesystem at all.

Together with gulp-latex, this is getting a few issue reports since it doesn't quite work the way people expect. I think the problem is that node-latex suggests it's a better fit for general latex needs than spawn + pdflatex — which it isn't really unless you want to avoid all the extra stuff latex spits out.

Contemplating a tmp: false flag that would just do work in the cwd and skip cleanup. Would make answering these issues easy, but then it's basically just rewriting spawn + latex.
