public interface LabelRenderer
The interface for things that can render labels for a line of information
about a sequence.
Renderers are always activated within the context of a particular SequenceRenderContext. A single LabelRenderer can be shared among many sequence panels, or added multiple times to the same panel. The renderer is required to request how much leading and trailing space it requires, as well as the depth (space orthogonal to the direction that the sequence is rendered).
