Fix some problems with importing OBJ and FBX #444

Closed sts1skj closed 2 years ago

sts1skj commented 2 years ago

For importing OBJ:

Preserve vertex order (issue #218 ).
When merging data with an existing shape, give option to update normals (issue #218 ).
Correctly handle faces with more than 4 vertices (issue #443 ).
Handle OBJ comments correctly.
Clean up a few things in ObjFile.{h,cpp}.
Don't duplicate vertices when normals or uvs are duplicated in the file.
Handle negative OBJ vertex/texture/normal indices correctly.

For importing FBX:

When merging data with an existing shape, give option to update normals (issue #218 ).
Split vertices with multiple UVs/normals. (Problem mentioned in issue #443 by ousnius.)
Swap x,y,z for normals the same way it already did for vertex coordinates (bug fix).

For exporting FBX:

Swap x,y,z for normals the same way it already did for vertex coordinates (bug fix).
