MediaPreferences

Remarks

⚠ One value rather than six fields on MediaContext, because these six come from one place and the other five do not. Width, height and scale are the surface's own and follow a resize; the gamut is the swapchain's; the colour scheme is the platform's appearance. These are the accessibility settings, which arrive together from whatever the host reads them out of — so a host sets one property and a window learns all six, instead of six properties each with its own change check and its own chance to be the one nobody wired.

⚠ Every default is the zero of its type, and that is load-bearing rather than tidy. A positional record struct's parameter defaults are what a constructor call omits, not what default produces — so an axis whose safe answer was not its zero would be safe everywhere except in the state this struct is most often in. See PointerCapability, which is the axis where that cost a bit.
