(polygons, beziers - just be rough and call them polyline/curve segments). > -----Original Message----- > From: "Carsten Haitzler"<ras...@rasterman.com> > To: "Enlightenment developer > list"<enlightenment-devel@lists.sourceforge.net>; Cc: > Sent: 2016-11-15 (화) 08:25:19 > Subject: Re: [E-devel] FW: FW: FW: FW: Propose a Eina_Path > > On Mon, 14 Nov 2016 22:54:15 +0000 Andrew Williams <a...@andywilliams.me> > said: > > > Rect seems to mirror quite well the path discussion I think - a data > > structure vs a graphical context... > > > > I see now how a non-gfx rectangle helps communicate data but can the > > graphical react not extend data structure type rect so they are more > > interoperable?
