      Description

      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
