.DESCRIPTION
Run it on a Windows machine with a GPU, alone, before tagging cultmath-unity-v*. The scratch
project is built outside the repository under -WorkRoot, references the package by a file: path,
and is deleted afterwards (-Keep leaves it). Exit 0 only when all three tests of SmokeTests.cs
and is deleted afterwards (-Keep leaves it). Exit 0 only when Unity exited 0, this run wrote the
results file (earlier ones are deleted before launch), and all three tests of SmokeTests.cs
passed: the C# calls, the real shader dispatched with the right output, and the broken control
shader detected.
