public IntMap<VertexBuffer> getBuffers() {
        return buffers;
    }
Returns a map of all {@link VertexBuffer vertex buffers} on this Mesh.
The integer key for the map is the {@link Enum#ordinal() ordinal}
of the vertex buffer's {@link Type}.
Note that the returned map is a reference to the map used internally,
modifying it will cause undefined results.

@return map of vertex buffers on this mesh.
