One of these structures is used to describe each separate instance of a BRL-CAD model database ".g" file.
dbi_filepath is a C-style argv array of places to search when opening related files (such as data files for EBM solids or texture-maps). The array and strings are all dynamically allocated.
Note that the current working units are specified as a conversion factor to/from millimeters (they are the 'base' in local2base and base2local) because database dimensional values are always stored as millimeters (mm). The units conversion factor only affects the display and conversion of input values. This helps prevent error accumulation and improves numerical stability when calculations are made.
