WMF: arcs on whole units, text by its font's ascent, no chords

Browse Source 
Arcs and pies are cut at whole multiples of 1/99 turn round the
ellipse's whole-unit centre and radii, rounded down, from the start ray
to the end ray. Text sits the font's ascent below its reference point
and is four fifths of it tall; its style is WMF-<face><n> on the
installed file of that face. CHORD records are not read.
