"outputdir" option for pkg dot2texi breaks on absolute paths & /some/ relative ones. The pdflatex -output-directory option is also mistreated

[bruceleerabbit]

I think I've encountered 3 bugs.

bug 1: absolute paths

This code fails: \usepackage[outputdir=/tmp/]{dot2texi} when compiled with pdflatex -shell-escape mygraph.tex, resulting in:

pdflatex: Not writing to /tmp/mygraph-dot2tex-fig1.dot (openout_any = p).

! I can't write on file `/tmp/mygraph-dot2tex-fig1.dot'.

(Press Enter to retry, or Control-D to exit; default file extension is `.tex')
Please type another output file name: 

bug 2: some relative paths

This code fails: \usepackage[outputdir=../work/]{dot2texi} when compiled with pdflatex -shell-escape mygraph.tex, resulting in essentially the same error as with the absolute path. Note the leading ../. When the relative path begins with a child directory there is no issue. The bug emerges if it traverses the parent directory.

bug 3: output paths specified on the commandline

This code fails: \usepackage{dot2texi} when compiled with pdflatex -shell-escape -output-directory=work mygraph.tex, resulting in:

Opening dot2tex stream mygraph-dot2tex-fig1.dotERROR    Failed to load file mygraph-dot2tex-fig1.dot
system returned with code 256


! LaTeX Error: File `mygraph-dot2tex-fig1.tex' not found.

Type X to quit or <RETURN> to proceed,
or enter new name. (Default extension: tex)

Enter file name: 

These problems frustrate complex projects where a Makefile is used with a work directory, in which case bug 3 manifests, and while the outputdir option has issues it seems impossible to work around.

Thanks for the bug reports. I'm afraid I don't have any quick fixes. My TeX-skills are rusty and I have not worked on dot2texi.sty for a very long time. Do you have any ideas for how to fix these issues?
