Support overflow-x/y

[bmweiner]

I am using Pandoc to generate a PDF with the Weasyprint engine. The Pandoc HTML template used in the document conversion has two CSS lines which are throwing warnings when building the PDF:

gap: min(4vw, 1.5em) (invalid value)
overflow-x: auto (unknown property)

This request is to support the min function and the overflow-x property. I also had a discussion with the Pandoc developers on this, but concluded it would be better suited as a feature request for your application.

Let’s track min() support in #357 and keep this issue for overflow-x and overflow-y.
