Changes:
This release enhances several tools and fixes numerous bugs since 7.12.4. NIRT now has several new formatting options available, including the ability to export tables of geometry data. Additionally, the tire tool has been improved to let the user specify whether a default rim should be modeled. Several MGED bugs were fixed, including changes to the dbconcat, dbbinary/bo, and nirt commands. The ray trace performance of the pipe primitive was significantly improved. The extrude primitive was extended to be more robust on invalid input geometry.
