Drawing pie slices and chords using filled arcs

Filled arcs draw either as a pie slice or as a chord, depending on the setting of the GCArcMode GC attribute. When the GCArcMode is set to ArcPieSlice, a pie slice is drawn.

| gc |
gc := CgGC default.
gc setArcMode: ArcPieSlice.
CgWindow default
    fillArc: gc
    x: 20
    y: 20
    width: 40
    height: 40
    angle1: 64 * 45
    angle2: 64 * 270.

When the GCArcMode is set to ArcChord, a chord is drawn.

| gc |
gc := CgGC default.
gc setArcMode: ArcChord.
CgWindow default
    fillArc: gc
    x: 20
    y: 20
    width: 40
    height: 40
    angle1: 64 * 45
    angle2: 64 * 270.
