load_scene has incorrect mesh name

[klattimer]

In an obj file with o MyObject accompanied by a mtl file with newmtl MyMaterial the mesh.name has the same value as mash.material.name.

Definitely it looks like the material name is used for the mesh name. I don't quite remember why this was done.

moderngl-window/moderngl_window/loaders/scene/wavefront.py

Line 111 in 200f2b9

mesh = Mesh(mat.name)

I think it's because vertices with the same material are by default consolidated into a single mesh. This is also reflected in the json/bin cache files when that is enabled. Will have to look at the possibilities later in 3.0. obj files are generally a nightmare to deal with due to the loose standard. The best path is likely to make a new loader using trimesh. Just archive or throw out the old one.
