    Added safety check for impossible sampling of singular points. · 3403f14e

    As per Brouwer's hairy ball theorem, any vector field on the 2-sphere
    has at least one zero. This implies that any implementation of
    TileAiming interface has at least one points where the aiming direction
    cannot be computed. The most typical example is aiming always towards
    North pole, for which both poles are singular points.
