+  per instance hot-tile for nearest samplers
+  atomic counters for tracking leaked buffers
+  Optimizationz for fetching column of pixels
+  Adaptive sampler pre-fetch caching
+  Micro performance optimizations of minimizing branching/function calls in
+  hot-spot pixel setting/getting code.
+
+Operations
+~~~~~~~~~~
+  mipmap tuning and performance improvements to gaussian blur
+  transform added dedicated code paths for nearest sampler
