Need for support for embedded SVG

[gkholman]

In the attached ZIP is an SWPX file with an embedded SVG ... and I'm told SVG is not supported, yet I can drag the included SVG file into the included sample DOCX without error.

Note there is a too-large PNG file embedded in the SWPX file ... I'm addressing that otherwise. It is there just to prove to myself that the embedded image code otherwise works.

This is my execution report:

I looked into this a little, and SVG is only supported in more recent MS Office versions. Office 2016 does not have it.

Office appears to embed SVG + a PNG fallback into files because of the lack of support in older versions.

Apache POI does not support SVG. This can of course be added to POI, but is likely to be a signficant amount of work.

Batik can be used to generate the PNG preview, although again this may be a good bit of work.
