Outputting

void output (const Focus& f, const unsigned short proj, real factor, const Transform& t) Function
Writes MetaPost code for the labels to out_stream. It is called in Picture::output() (see Picture Reference; Outputting). Users should never need to call this function directly.

When Picture::output() is invoked, the MetaPost code for Labels is written to out_stream after the code for the drawing and filling commands. This prevents the Labels from being covered up. However, they can still be covered by other Labels, or by Shapes or Labels from subsequent invocations of Picture::output() within the same figure (see I/O Functions, for descriptions of beginfig() and endfig()).
