v1.145.0

Added

• bn.ResultSVG, a result type for SVG files. The report draws each sample as a base64
  <img>, so an SMIL animation in the file plays. It is a sibling of ResultImage, not a
  subclass, and has the same storage spec. Rerun warns and skips it.

Changed

• The Cartesian sampling animation in each report is now an animated SVG, not an APNG.
  render_animation writes cartesian_*.svg. Over 8 benchmark sweeps, the animation adds
  85% fewer bytes to a gzipped report and renders 87% faster. The gallery page
  example_cartesian_animation drops from 10315 KiB to 167 KiB gzipped. The PIL renderer
  functions render_shape_to_image and TimelineShape.render_strip_image are removed.
• A long stacked dimension (2 × 2 × 240) is 23% larger on disk than its APNG (3066 against
  2494 KiB), though 5× smaller gzipped. PR #1192 fixes this case.
