Detailed Description

Holds semaphores used for synchronizing image acquisition and rendering.

Vulkan implementation of the platform-agnostic Swapchain.

Each frame-in-flight uses a pair of semaphores:

• ImageAvailableSemaphore: signals when the swapchain image is ready to be rendered to.
• RenderFinishedSemaphore: signals when rendering is complete and ready for presentation.

Handles Vulkan-specific swapchain creation, synchronization, resizing, and presentation.

Constructor & Destructor Documentation

VulkanSwapchain()

Raven::VulkanSwapchain::VulkanSwapchain	(	u32 *	width,
		u32 *	height,
