Getting the capabilities of a presentation surface

When we create a swapchain, we need to specify creation parameters. But we can't choose whatever values we want. We must provide values that fit into supported limits, which can be obtained from a presentation surface. So in order to properly create a swapchain, we need to acquire the surface's capabilities.

How to do it...

1. Take the handle of a selected physical device enumerated using the vkEnumeratePhysicalDevices() function and store it in a variable of type VkPhysicalDevice named physical_device.
2. Take the handle of a created presentation surface. Store it in a variable of type VkSurfaceKHR named presentation_surface.
3. Create a variable of type VkSurfaceCapabilitiesKHR named surface_capabilities.
4. Call vkGetPhysicalDeviceSurfaceCapabilitiesKHR(physical_device, presentation_surface, &surface_capabilities) for which provide the handles of the physical device and a presentation surface, and a pointer to the surface_capabilities variable.
5. If...
