Giant orcid logos in docx output

[ch728]

My docx output has giant orcid logos in it. I do not have this problem in the html or pdf output.

The issue is that these are svg images and docx readers (especially older versions of Word) do not have great svg support. There is some historical discussion of that in #40. This is a general pandoc issue, and there was an update within the past week to improve svg docx support jgm/pandoc#4058.

I tested your manuscript. Word 2016 on Windows doesn't render the svg images at all:

Some users have modified content/00.front-matter.md to remove these images or customize the build script to exclude the images when converting to docx. Others manually delete them from the docx. We don't have a good general solution yet. The next step may be to test the next pandoc release to explore its updated support.

This can be fixed on the rootstock side by manually defining the size of the SVG images in content/00.front-matter.md. I used 16px because that's the size defined in the SVG files.

@agitter Do you think the workaround is benign enough to merge in to rootstock?

[dhimmel]

We used to include height="13px" width="13px" but that was changed in 658bcd7. Seems like we might want to add them back.

@vincerubinetti did you want to weight in? Do you know whether these logos should be 13px or 16px?

[vincerubinetti]

Either is fine.

@twrightsman do you want to make a PR to rootstock with this change?
