* This is better than testing by platform/platform version, because we can check
specifically for extensions and avoid running a test we know will fail because
extensions aren't supported.
* This is useful when writing automated tests that want to test the output of
rendering which only happens to outputs, such as mesh rendering, or could
potentially be bypassed with direct readback like GetTextureData vs rendering
a texture.
* 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.
