0.33.0 — ImageLightbox maxZoom cap

Added

• ImageLightbox maxZoom prop. Caps how far the extended zoom controls can
  magnify, as a multiple of the image's natural resolution: maxZoom={1} = 100% of the
  source's real pixels (1 source px = 1 screen px), maxZoom={2} = 200%. The modal
  always opens fitted to the viewport; this only bounds zoom-in. An image whose fitted
  size already exceeds the cap can't be zoomed in (the control disables). Per image in a
  gallery. Reads the natural pixel size from width/height or the loaded image; until
  that's known the previous 5×-the-fit cap applies. The toolbar percent stays
  fit-relative (fit = 100%).
