Make bounding boxes for character based on line-height:0 rather than line-height:normal (the other varried too much from browser to browser and failed to match the internal dimensions). The HFUZZ and DFUZZ may need to be adjusted, and may need to be made browser specific (argh), but that might be able to be done through CSS.
