Re: object-fit/view-box for element content

Hi,

I would like to add a use case for this, especially since it came up on the
DPUB IG call yesterday (in context of Houdini use cases, but still).

A similar behavior is common in math rendering. For example, the MathML
spec has `overflow=scale`
<https://www.w3.org/Math/draft-spec/mathml.html#chapter2_interf.toplevel.atts>
for
this purpose -- although it's not implemented in any (web-based) rendering
system I know of.

Best regards,
Peter Krautzberger, MathJax.
