The display options a person set in the system’s accessibility settings: larger text, less motion, less transparency, more contrast, bold text, inverted colors.

DrawCommandFn: Re-export the UI crate so applications can depend on a single crate. A draw command records into a scope the CONSUMER provides, instead of returning a freshly allocated primitive vector. This is the boundary that lets recording storage live with the command’s stable identity and be reused frame over frame (the retained draw-command recorder), rather than being reallocated, moved, and dropped on every execution.

ScrollSettlePolicy: Re-export the UI crate so applications can depend on a single crate. Remaps where a scroll comes to rest once the user’s interaction ends — the UIScrollView targetContentOffset analog. Receives the naturally proposed rest offset (the fling’s predicted end, or the current offset for a plain release/wheel idle) and the release velocity in offset units/sec; returns the offset the scroll should settle at. Used e.g. by the liquid nav bar to snap out of the large-title collapse band so the title never rests half-faded.
