Description of problem:

The (sole) test is failing on s390x (the sole big-endian architecture). This is clearly a case of an endianness mixup; trimesh and opencascade are involved too, and it’s not clear exactly where the problem is.

Version-Release number of selected component (if applicable): 0.0.12-4


How reproducible:

Steps to Reproduce:
1. Remove s390x from ExcludeArch in the spec file.
2. Run fedpkg scratch-build --srpm --arches s390x (or fedpkg mockbuild --root fedora-rawhide-s390x, with qemu-user-static installed).

Actual results:
