Potential bug in python pmeshlab.Mesh class __init__ relating to texture coordinates

[nikolas-claussen]

When initialized using a list of faces, (the face_list_of_indices argument), pmeshlab.Mesh mangles texture information (passed via the v_tex_coords_matrix argument). Example:

vertices_test = np.array([0.0,0.0,0])
textures_test = np.array([0.5,0.5])

mesh_test = pymeshlab.Mesh(vertex_matrix=vertices_test, 
                           face_list_of_indices=[],
                           v_tex_coords_matrix=textures_test)

mesh_test.vertex_tex_coord_matrix()

returns array([[0., 0., 0.]])

What erroneous texture is returned by mesh_test.vertex_tex_coord_matrix() appears to depend on the datatype of the provided texture, with results being either 0 or very large numbers.

If you use the face_matrix argument for initialization, there is no problem.
