In one test, this reduces tiling time by about 8% when running a tile iterator on a tile that is slightly smaller than the native size (224 square rather than 240 square). Of the time reduction, some of the speed is based on non-format specific gains and some specifically on the tiff tile source; roughly 3% is the non-format specific, and 5% is tiff specific.

Note that these gains become less significant as tile size goes up.
