I have recently read, that you can create a swapchain with the imageUsage set to VK_IMAGE_USAGE_TRANSFER_DST_BIT which result in it not using the its images a the color attachment.
That means i have to create my own images for the color attachment and add them to the VkFramebuffer.
How do i now set those images as the render targets of a VkCommandBuffer and how do i copy the image into the swapchains image for presentation?
