The original caching logic for sample locations wishfully assumed that the GPU would always use the same sample pattern for render targets that had the same number of samples. It turns out we can't rely on that. This change improves the caching logic to handle mismatched simple patterns with the same count, and adds a unit test that emulates different sample patterns observed on real hardware.
