The base class for WWT annotations.
Annotations are draw by being added to an AnnotationBatch. Note that a given annotation
can be included in multiple annotation batches, though each batch will then create its own
set of graphics primitives for that annotation.
Annotations have a coordinateTransform field which define how their (2D) coordinates are mapped
into 3D space. By default, annotations assume that they have equatorial coordinates (RA/Dec).
For convenience, we provide the transform for drawing annotations in galactic coordinates.
