Description

Adding view format changing as a downlevel flag was missed on the original PR, so an extra bit of data wasn't passed down to vulkan.

Testing

Tested using the view format aliasing test, thanks for that test!

LGTM, ideally we'd also make use of VK_KHR_image_format_list but we can do that later, I'll open an issue.
