How to handle the result of Surface::get_current_texture.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Present

Texture is usable — render into it.

Reconfigure

The swapchain is stale or gone (Outdated/Lost): reconfigure the surface and try once more THIS frame.

SkipAndRetry

Transient (Timeout): skip the frame, but ask for another one.

Skip

Skip the frame with no follow-up (Occluded/Validation): the window is not visible / the app must fix the validation error, and a self-requested redraw would just burn the CPU.
