    unknown type name 'VkRayTracingPipelineCreateInfoKHR'; did you mean 'VkRayTracingPipelineCreateInfoNV'?
    KHR is Beta, NV is not.

1. Download the latest tarball from https://vulkan.lunarg.com/sdk/home

2. Unpack the tarball and run `./install_vulkan.py`

    - If you see a complaint about `/usr/local/lib/cmake`, do a force install.
    - It might complain about permissions, in which case you could do
      `sudo chown -R $(whoami) /usr/local/bin`.

3. To set environment variables such as VK_ICD_FILENAMES etc, do `source MY_SDK/setup-env.sh`.

4. If you see a dialog like "Apple cannot check it for malicious software..." then you might need
   enable the dylib by ctrl-clicking it in Finder, clicking open, then clicking open again.


Image layout validation is done in multiple places throughout the core_validation layer. When it is
possible to know the layout at command buffer record time (for example if an image layout transition
was done earlier in that command buffer), the current image layout is compared against the
binding/usage in copy, dispatch, and draw calls. Where the image layout state cannot be determined
that check is deferred until queue submission of the command buffer, when the required state of the
image layout from the point of view of the command buffer is compared to the current/global state of
the image layout.
