Vulkan Descriptor Sets and Bindings

Write a C program that models a Vulkan descriptor set layout and pool.

Requirements:

• Define structs for DescriptorBinding (binding number, type, count, shader stage) and DescriptorSetLayout
• Create a descriptor set layout with these bindings:
  • Binding 0: UNIFORM_BUFFER, count=1, stage=VERTEX (camera matrices)
  • Binding 1: COMBINED_IMAGE_SAMPLER, count=1, stage=FRAGMENT (diffuse texture)
  • Binding 2: COMBINED_IMAGE_SAMPLER, count=1, stage=FRAGMENT (normal map)
  • Binding 3: UNIFORM_BUFFER, count=1, stage=FRAGMENT (light data)
• Print the layout showing binding, type, count, and stage for each descriptor
• Create a descriptor pool requirement summary:
  • Count how many UNIFORM_BUFFER descriptors are needed
  • Count how many COMBINED_IMAGE_SAMPLER descriptors are needed
  • Assume 100 material instances (each material gets its own descriptor set)
  • Print total pool requirements
• Model a second descriptor set layout for per-object data:
  • Binding 0: UNIFORM_BUFFER, count=1, stage=VERTEX (model matrix)
• Print a pipeline layout summary showing which sets are used for what data frequency
