I've made a start on the code just for my project. Will provide that to the team once it is settled and it can be adjusted to fit the designs

Dont alot of work on this within a project. I'll share what has been done. It takes into account needing solid dark areas, split areas, all sorts.

Closing in favour of #207 as it contains a much more in depth proposal.
