> I may be missing something but in 19.171 draw:formula we have:
> logheight The height of the svg:viewBox attribute in 1/100th mm is
>          used.
> logwidth The width of the svg:viewBox attribute in 1/100th mm is used.
> The name involved here is strange since no logarithmic transformation
> seems to be happening. But that is not my issue.
> The svg:viewBox does not carry any units. In fact it is the whole point
> of the viewBox attribute in svg to establish a unit less coordinate
> system such that as the size of the viewport changes the graphic change
> accordingly without its coordinates (in viewBox coordinates) changing.
> So it is completely unclear to me how logheight and logwidth are
> intended to be calculated.
> Note that logwidth and logheight are similarly specified for 19.179 draw:handle-position
