Release 4.11.5

Release: Fix fill_holes with face attributes (#2518)

Trimesh.fill_holes was adding new faces but haphazardly managing the
bookkeeping: it broke len(mesh.faces) == len(mesh.face_attributes[n])
if there were any holes filled.

• add Trimesh.extend_faces which moves the bookkeeping of "preserve
  cached face normals to avoid recalculating, pad face colors, pad face
  attributes" to a generic mesh attribute in the same vein as
  mesh.update_faces.
• refactor the tesselation of the holes in repair.fill_holes to use
  triangulate_quads which implemented the hole filling logic but better.
  Switch the winding search to a numpy indexing trick for new faces.
• Have geometry.triangulate_quads use the preexisting
  util.triangle_fan_to_faces which uses numpy instead of a list
  comprehension and is heavily used and tested in the codebase.

Also:

• try to test and fix #2516

Release 4.11.4

Release: Simple endian tests (#2512)

Even if we can't fully support other endian platforms, imports and
exports should explicitly set endian-ness of outputs.

• Adds a make test-arch which runs a subset of test on qemu/docker to
  catch simple problems on little-endian and 32bit platforms
  • Fixes #2511
  • Fixes #2510
• Adds fix from #2506 which implemented Line.closed setter to
  auto-close polylines when passed.
• Audit use of np.einsum/np.dot from good discussion in #2514. My
  conclusion was that numpy.dot is probably not the culprit and too core
  to avoid. As part of looking into this I benchmarked our other uses of
  np.einsum against simple numpy operations, it was on average ~2x
  slower. I also tried the `np.einsum(... optimize=True) as discussed in
  this interesting
  post
  but for the trimesh use cases of very simple expressions this was
  substantially slower in every case I measured.

Release 4.11.3

Release: Fix For Open Paths (#2507)

• release #2505
• switch while loop to bounded for loop in the traversals logic

Release 4.11.2

Hotfix for new ruff release (#2503)

Fix for new ruff rule in 0.15.0 blocking release.

Release 4.11.1

Release: Fix WebP Export (#2499)

• test and release #2498

Release 4.11.0

Release: Extensions (#2497)

• capture STDERR to fix #2495
• release #2492
• release #2493
• moves trimesh/exchange/gltf.py to
  trimesh/exchange/gltf/__init__.py which is identical for import users,
  but lets us add the additional extensions.py next to it.

Release 4.10.1

Release: Projected Precise Mode (#2491)

• release #2490 as discussed in #2488 doing minor cleanup below the
  precision threshold before unioning every triangle in projected(... precise=True)
• release #2487 cleaning up the logic in
  trimesh.grouping.group_distance to be more coherent.
