Our gfxPattern cache is currently way too specific, which causes lots of unnecessary cache misses. The only thing that we actually need to key on is the color stops. This switches the cache to hold GradientStops instead of gfxPatterns. This improves our cache hit rate and is simpler. It also avoids doing caching when not using Azure, which currently has no benefit.
