Descriptor Sets - Vulkan Game Engine Tutorial 20

Vulkan uses descriptors as a way to provide resources to our shader programs. Descriptors cannot be bound to a pipeline individually, and must be grouped into a set. Additionally, before pipeline creation, a descriptor set layout must be provided. A descriptor set layout acts as a blueprint, telling the pipeline how many descriptors will be bound, and what types of resources each descriptor uses.

In this tutorial, we create abstractions for descriptor sets, descriptor set layouts and descriptor pools, to make these objects easier to work with within the engine. We create a descriptor set layout that contains a single buffer descriptor, and use this to bind the uboBuffer for use within the vertex shader.
