* In heavy D3D11 workloads the refcounting overhead especially during fast
binding changes was significant. Refactoring the refcounting to work on a
different model and deferring destruction of objects removes most of the
overhead.
* This helps catches cases where a discarded image is accidentally used and in
many cases may still have valid data. Particularly on Vulkan this is relevant
for DONT_CARE renderpass load and store ops.
* This doesn't test every edge case, but it is a simple smoke test that ensures
any format can at least get consistent accurate results out.
* Further work is needed to test the different failures, overdraws, primitive
IDs, and all the other specific checks in the history.
* If we create in a bare pointer then just cast to a smart pointer, it adds a
ref instead of stealing it. Just only allow creating smart pointers in the
first place.
* 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.
