+ add outer ring (selectability will come next)
* improve scaling by deriving coefficients from screen (mostly width, but height too for centering)
* fix twelfth hour going fully dark instead of fully lit with a trickier modulo expression
- Abandon "TDC petal first"
+ Add counterclockwise capability to "pies" (circles of petals)
* Use this new ability to redo minutes to go CCW from right of BDC, as if you were reading MSB-first LTR, but rolled down over the hub
Concept get! Much, much more to follow, including complications
