Description of Change(s)
Modifying shader generation on HgiVulkan to flip the UV y coordinate when looking up textures so Vulkan shaders behave like on other backends.
Fixes Issue(s)
Aovs processed by UsdImagingGl tasks (Color correction, selection, etc.) appear flipped vertically from their initial state after processing when using Hgi Vulkan.
