    Class
    Description
    A curve drawn on the sky.

    Two ways to define one, and the first is what a daily path is:
    - as a CIRCLE about an axis: every direction at a fixed angle from the axis.
    A base class for objects that are placed in the sky rather than on the map.

    An object is anchored in one of two ways:
    - by DIRECTION (azimuth and altitude), with an optional distance.
     
    A flat, camera-facing object in the sky: a disc, a point of light, an icon overhead.

    Its size is given either as an ANGULAR size in degrees - which is what a real body has, so it
    grows and shrinks with the field of view like everything else in the world - or as a fixed
    SCREEN size in pixels, which is what an icon or a marker wants.
