/* This file defines the core libxmi API, consisting of:
1. miDrawPoints, miDrawLines, miFillPolygon.
2. miDrawRectangles, miFillRectangles.
3. miDrawArcs, miFillArcs. Also the reentrant miDrawArcs_r.
Each of these is a wrapper around an internal function that takes as first
argument a (miPaintedSet *). A miPaintedSet struct is a structure that is
used by Joel McCormack's span-merging module to implement the
`touch-each-pixel-once' rule. See mi_spans.c and mi_spans.h. */
