* The spec says we only return a function pointer for device or device-child
functions. In practice the loader wraps instances and physical devices so when
calling a direct GDPA returned function the loader won't unwrap it so we won't
get our proper wrapped objects and will crash.
* It's not particularly scalable and can be brittle to driver changes, and we
can use targeted specific pixel tests to check what we really want - to see if
the output has rendered correctly.
* Overlay tests still check files directly - this is a future refactor to
remove.
* Previously if a handle was reused, and then a stale descriptor referencing the
old handle was removed it would remove the *new* object from the list of
referenced resources. This could cause a resource to be not included in a
capture if nothing else added a new reference.
* Instead of tracking their lifetime with that object, we move the lifetime
tracking into the parent VulkanGraphicsTest and destroy them all at the end. A
single handle can optionally be free'd on its own.
* Visual assist comes with a pre-defined interpretation of TEST() for
googletest, which conflicts with ours. We can't seem to override it with a
va_stdafx.h even
