That's definitely true for conic curves, as this is defined in
the TrueType spec. This corresponds to a "virtual" on point
located at the exact middle of two successive off points.

Note that some fonts don't even use a single on point to
define certain contours ! Have a look at the function
FT_Decompose_Outline which should be located in
"freetype2/src/base/ftobjs.c" to see how FT_Outlines are
parsed.

TT_Outline are similar, only simpler :-)
