* encountered a newly added Vulkan error message.
* You want to add it to this enum now.
*
* Because the Vulkan people don't make adding this too easy, here's
* the process to manage it:
* 1. go to
* https://github.com/KhronosGroup/Vulkan-Headers/blob/main/include/vulkan/vulkan_core.h
* 2. Find the line where this enum value was added.
* 3. Click the commit that added this line.
* 4. The commit you're looking at now should also change
* VK_HEADER_VERSION, find that number.
* 5. Use that number in the #ifdef when adding the enum value to
* this enum.
* 6. For the error message, look at the specification (the one
* that includes all extensions) at
* https://www.khronos.org/registry/vulkan/specs/1.0-extensions/html/vkspec.html#VkResult
* 7. If this value has not been added to the specification yet,
* search for the error message in the text of specification.
* Often it will have a description that can be used as an error
* message.
* 8. If that didn't lead to one (or you are lazy), just use the
* literal string of the enum value as the error message. A
* GTK developer will add the correct one once it's added to the
* specification.
