For when there's nothing to present to. Instead of a surface and swapchain, it renders into images of its own through the VulkanPresentation interface libretro uses, picking the graphics queue without a surface. Acquiring and presenting signal and wait on the frame's semaphores with empty submits. Co-Authored-By: Claude Opus 5.5 (1M context) <[email protected]>
