NVIDIA Vulkan Trace Rays Indirect Tutorial

This is an extension of the Vulkan ray tracing tutorial.

We will discuss the vkCmdTraceRaysIndirectKHR command, which allows the width, height, and depth of a trace ray command to be specifed by a buffer on the device, rather than directly by the host. As a demonstration, this example will add colorful lanterns to the scene that add their own light and shadows, with a finite radius of effect. A compute shader will calculate scissor rectangles for each lantern, and an indirect trace rays command will dispatch rays for lanterns only within those scissor rectangles.
