Could anyone point me to some ref/example on how to program
a Bezier curve, especially wrt to the use of BezPoint in the fill_bezier
and draw_bezier function of the diarenderer ?

It's a bit funky. There's some explanation in lib/geometry.h, and a
generic implementation using lines in lib/diarenderer.c. To create a new
bezier object, look at the example in plug-ins/xfig/xfig-import.c, which
creates a bezier curve from xfig format.
