Creating a layered 2D image with a CUBEMAP view

A quite common example of images used in 3D applications or games are CUBEMAPs, used for simulating an object reflecting its environment. For this purpose, we don't create a CUBEMAP image. We need to create a layered image and through image view, we tell the hardware that it should interpret its layers as six CUBEMAP faces.

How to do it...

1. Take a handle of a logical device. Store it in a variable of type VkDevice named logical_device.
2. Choose the size of an image and remember it must be square. Save the image's dimensions in a variable of type uint32_t named size.
3. Select the number of the image's mipmap levels. Initialize a variable of type uint32_t named num_mipmaps with the chosen number.
4. Think about all different scenarios in which the image will be used. Store the logical sum (OR) of all these usages in a variable of type VkImageUsageFlags named usage.
5. Create an image of a VK_IMAGE_TYPE_2D type, a VK_FORMAT_R8G8B8A8_UNORM format, six layers, and...
