A couple of different approaches to this have been discussed before. I
think the most generic solution was to implement a 0 DETAIL <level>
meta-command, that would identify the detail-level of the following
lines. A 0 detail level indicates that the follow lines must always be
rendered. Higher levels indicate "less important" or "more detailed"
lines. Renderers could use the detail-level information to control when
and how to render lines - only rendering the lines necessary, perhaps
queueing lines for rendering based on the detail level.
