pDb == 0 specifies that this file search is not related to a database.
If pDb != 0, call pDb->getFilename() to determine the path to the DGN file associated with the database.
The typical search order is as follows:
- The filename itself.
- The current directory.
- The drawing directory (for shx font, image, and xref files).
- The Windows fonts directory (only for TTF fonts on Windows).
