pub const SURFACE_FORMATS: [TextureFormat; 2];Expand description
Every swapchain format select_surface_format will configure a surface
with — a membership set, not a preference order.
Both are 8-bit-per-channel unorm formats the engine’s pipelines are built
for, and the engine warms itself for whichever one the surface hands over,
so neither is privileged. Which of the two a platform reporting both lands
on is the surface’s own preference order — see select_surface_format.
