Iff an mesh file is found at `filepath`, returns a :map:`TriMesh`

Parameters
----------
filepath : `str`
A relative or absolute filepath to an image file.
landmark_resolver : `function`, optional
This function will be used to find landmarks for the
mesh. The function should take one argument (the mesh itself) and
return a dictionary of the form ``{'group_name': 'landmark_filepath'}``
Default finds landmarks with the same name as the mesh file.

If ``False``, don't search for textures.
