These feel like work-arounds for an API that wasn't designed for these use cases. visibility:hidden is the correct solution for the use-case presented (measuring things that aren't visible). HTML/CSS has a further use-case in-between visibility:hidden and display:none where you want something to not be visible or affect layout in any way but still generate boxes and run general house-keeping, like incrementing counters and keeping animations going. As far as I can tell this isn't necessary in SVG, as it's trivial to make the layout algorithm ignore a box, and so just using visibility:hidden is fine. ~TJ
