* 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.
* 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
* This will let us run multiple windows (and multiple threads) relatively
easily.
* The hammer is fairly big, we move some things into the window that don't need
to be there necessarily if we have multiple windows on a single thread, but it
keeps things simple.
* Instead of only doing a very lightweight check to see if the API is available
up-front, we now share the API initialisation among all API tests far enough
to determine availability of extensions, features, etc. Then we can precisely
determine which tests are available and which aren't before running.
* Built entirely independently of the main renderdoc build (for now).
* Contains python scripts & framework for running tests on a renderdoc build,
which will be run nightly.
