[x3d-public] X3DJSAIL update: improved output when exporting ClassicVRML/VRML97 models

Sat Jul 6 18:10:34 PDT 2024

Also searching for “roundtrip” crashes my browser as well.

Probably I’ll drop to the file system or build.xml to see how you are doing
roundtrip.  I see evidence of cleanup at this point.

Maybe I downloaded too many files to my phone.
