Well adding a new function is ok, but I can not see what problem
this solves ... what was causing problems for you was most likely
the fact that I did number the points the wrong way round ... if
you draw them C B A and then add f e d things should work ...
by using the primitive operations I have defined in rrd_gfx and
bilding on them instead of going into rrd_gfx and adding code there
would be that the whole graphing engine bit stays small and easy to
manage ... so at least I would suggest zou use the rrd_gfx
primitives in the gfx_arc_sect code instead of art_ primitieves ...
if this is ok with you I will change the code ...
