This library is a utility which tracks all the required details so that applications can have a simplified interface to the swapchain. * Creation - Pass a SwapchainBuilder to specify how the swapchain should be created. * Recreation - Recreates the swapchain upon request. * Semaphores - Handles creation and usage of them, a particularly thorny part of swapchain management. Additional Libraries: - DelayedDeletionQueue; for easy deletion of objects currently in flight - ImagelessFramebufferBuilder; for easy creation of imageless framebuffers The new code lives in VkSwapchainManager.h, so its easier to distinguish the core parts of vk-bootstrap from the optional.
