How to do it...

1. Prepare vertex data for the quad's geometry. Use the following values for four vertices (add texture coordinates if needed):
   • { -1.0f, -1.0f, 0.0f } for top left vertex
   • { -1.0f, 1.0f, 0.0f } for bottom left vertex
   • { 1.0f, -1.0f, 0.0f } for top right vertex
   • { 1.0f, 1.0f, 0.0f } for bottom right vertex
2. Create a buffer that will serve as a vertex buffer. Allocate a memory object and bind it to the buffer. Upload vertex data to the buffer using a staging resource (refer to the Creating a buffer, Allocating and binding memory object to a buffer, and Using staging buffer to update buffer with a device-local memory bound recipes from Chapter 4, Resources and Memory).
3. Create a combined image sampler. Remember to provide valid uses ...
