TileDisplay tests need some attention
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
Some of the baselines are invalid and results aren't stable across platforms.
The TileDisplay3DTesting-1x2 test has been disabled, as it was failing to recognize valid baselines in ExternalData. Something is very fishy about it. This should be fixed and re-enabled at some point.
The remaining TileDisplay tests remain enabled.
