Threaded generation of software paths
All information needed by the thread is captured by the prepare callback object, the lambda captures a pointer to that, and does the mask render. Once it's done, it signals the semaphore (also owned by the callback). The callback defers the semaphore wait even longer (into the ASAP upload), so the odds of waiting for the thread are REALLY low. Also did a bunch of cleanup along the way, and put in some trace markers so we can monitor how well this is working.
