Detailed Description

Creates a swapchain and keeps it up to date with the window.

If the window is resized or ezGameApplication::cvar_AppVSync changes and onSwapChainChanged is valid, the swapchain is destroyed and recreated. It is up the the application to respond to the OnSwapChainChanged callback and update any references to the swap-chain, e.g. uses in ezView or uses as render targets in ezGALRenderTargetSetup. If onSwapChainChanged is not set, the swapchain will not be re-created and it is up to the application to manage the swapchain and react to window changes.
