I can help add pdf preview support #231

I can help add pdf preview support, if no one is working on it.

Here's the idea.

  1. Hack ranger-preview-buffer.
  2. Add a condition for pdf files.
  3. In that condition, generate a cache image that shows the first page of the pdf by running pdftoppm -f 1 -l 1 -scale-to-x 600 -scale-to-y -1 -singlefile -jpeg -tiffcompression jpeg -- "/path/to/pdf.pdf" "/tmp/cache.jpeg". (Code taken from here)
  4. Preview that image.
