Selecting a number of swapchain images

When an application wants to render into a swapchain image, it must acquire it from the presentation engine. An application can acquire more images; we are not limited to just one image at a time. But the number of images that are available (unused by the presentation engine at a given time) depends on the specified presentation mode, the application's current situation (rendering/presenting history), and the number of images--when we create a swapchain, we must specify the (minimal) number of images that should be created.

How to do it...

1. Acquire the capabilities of a presentation surface (refer to the Getting capabilities of a presentation surface recipe). Store them in a variable of type VkSurfaceCapabilitiesKHR named surface_capabilities.
2. Create a variable of type uint32_t named number_of_images.
3. Assign a value of surface_capabilities.minImageCount + 1 to the number_of_images variable.
4. Check whether the value of the maxImageCount member of the surface_capabilities...
