As often happens with you and I, we rarely use the same words but
frequently agree. Each of us has described the same rendering
mechanics, but in different ways.
Of course whether re-rendered on resize in a script or in C any SVG can
be made to look good. But given how much faster C is, and since SVG is
already provided in LC's underlying Skia, why not use it?
Mark Waddingham has already submitted the pull request, so at this point
it's not like we need to wait much longer to have a fairly optimal SVG
rendering option in LC.
