SUMMARY="Vulkan loader and validation layers"
DESCRIPTION="
Vulkan is an Explicit API, enabling direct control over how GPUs actually work. No (or very little)
validation or error checking is done inside a Vulkan driver. Applications have full control and
responsibility. Any errors in how Vulkan is used often result in a crash. This project provides
standard validation layers that can be enabled to ease development by helping developers verify
their applications correctly use the Vulkan API.
