I would have said that we should just use convertLength to match what we pass in
HTMLMarquee. However we are only interested in numbers as we filter them down in
validUnit below and we don't have a convertNumber function so I guess I could
live with either converter.

convertLength passes a Length into the RenderStyle setter which fails
compilation. I'll go with convertNumberOrPercentage.
