Clearing a depth-stencil image

Similarly to color images, we sometimes need to manually clear a depth-stencil image outside of a render pass.

How to do it...

1. Take the command buffer that is in a recording state and has no render pass currently started in it. Using its handle, initialize a variable of type VkCommandBuffer named command_buffer.
2. Take the handle of a depth-stencil image and store it in a variable of type VkImage named image.
3. Store the value representing the layout, in which the image will have during clearing, in a variable of type VkImageLayout named image_layout.
4. Create a variable of type std::vector<VkImageSubresourceRange> named image_subresource_ranges, which will contain a list of mipmap levels of all the image's and array layers, which should be cleared. For each such range, add a new element to the image_subresource_ranges vector and use the following values to initialize its members:
   • The depth and/or stencil aspect for aspectMask
   • The first mipmap level to be cleared...
