How to draw custom lines in webgl ?

Hi,
how do I modify webglLineProgram to draw a path instead of a line?

using SVG I can use native and draw a path connecting A to B (fromPos and toPos in graphics.placeLink(function(ui, fromPos, toPos) { } )

Any simple way to do it in native webGL ?

Start by examining the WebGL line implementation referenced as webglLineProgram and compare it with the SVG path behavior in graphics.placeLink(function(ui, fromPos, toPos) { }). Determine whether the existing native WebGL renderer can represent a path connecting the supplied positions; done means documenting or implementing a clear way to draw that path.
