SupportedImageProperties & GetSupportedImageProperties ()bool SupportsImmediatePresentMode ()Vulkan defines immediate as presentation that doesn't wait for the vblank period to update
the current image; so, switching buffers can result in tearing.
Importantly, with immediate update, the previous image should also become immediately
available for reuse, making this mode useful for measuring maximum render rate.
Flatland and display drivers don't support unsynchronized updates, so we approximate
it by ignoring fences. This allows the client to reuse an image before its release
semaphores are signaled, so the client doesn't wait to acquire a swapchain buffer.
We also send a fake acquire fence to remove any associated delays.
The difference is in the amount of tearing:
- spec: less tearing, just the transition from one complete image to another
- implementation: more tearing, the visible image may be incomplete
