Render test comparison refactor

[kwokcb]

Goals

• Portable / reusable data model. Store individual or comparisons. Proposed JSON for desktop, web , mobile
  • 100% self contained.
• Separable analysis tooling and storage utiles
  • hashing encoding, vs image diff requirement for rms, faster error tolerance filtering.
  • comparison metric: rms, hash
  • compression / size reduction. Base64 encoding, jpeg
  • transmittable format. Current html results are much too large to transmit / embed efficiently or at all.
• modern and performant math, image library
  • current most robust ‘ complete choice is OpenCV (js and python Gpu accelerated).
  • Aswf specific targets can be used but is not restricted to this.
• allow for user customizable views of data
  • markdown for widest distribution and GitHub compatibility.
  • html for specific styling / formatting. Allow legacy 1990’s style html but also make responsive so can view properly on all devices
  • utlilities builtto use json model data
• client vs server side action options. Does not require full preprocessing. E.g can do analysis on client side for individual tests vs requiring full reruns.
