In the past we discussed only 2 resolutions, in which case providing
another set of fringe bitmaps sounds plausible.  But you seem to be
talking about supporting any arbitrary scale, not just the double one
of HiDpi displays, and that calls for a different implementation that
we should IMO think over up front.
