* We also fix a number of issues that could cause incorrect formats to be
generated.
* Test cases added for D3D11/GL/Vulkan to test different struct types. These
aren't automated at the moment because most of the code they're testing is in
the UI itself.
* 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.
