Creating a logical device with WSI extensions enabled

When we have created an Instance with WSI extensions enabled and have found a queue family that supports image presentation, it is time to create a logical device with another extension enabled. A device-level WSI extension allows us to create a swapchain. This is a collection of images which are managed by the presentation engine. In order to use any of these images and to render into them, we need to acquire them. After we are done, we give it back to the presentation engine. This operation is called a presentation and it informs the driver that we want to show an image to the user (present or display it on screen). The presentation engine displays it according to the parameters defined during swapchain creation. And we can create it only on logical devices with an enabled swapchain extension.
