Graphics tests

This directory contains automated tests that cover Fuchsia's graphics stack, mostly via the Vulkan API. C++ tests should prefer Vulkan-Hpp to direct use of the Vulkan C API.

The tests in this directory cover Fuchsia-specific Vulkan functionality. Graphics tests against the Vulkan API that don't have any Fuchsia-specific bits should be submitted to Vulkan's Conformance Test Suite (CTS).
