If there only was a cheaper method of creating polygons for lines... createAreaGeometry() creates a perfect (but polygon-count heavy and thus expensive) geometry while we just need a geometry good- enough for the target device... something like "emboldening" a line. I know that approach is not perfect from a theoretical standpoint but e.g. flattening "wild" curves, then expanding perpendicular to both sides and then removing self intersections would be good enough for typical linewidths on a display. And it would create only few extra polygons if at all. That is no OOx3.1 material though, maybe I'll have a go at it for 3.x. E.g. freetype's FT_Outline_Embolden does it in a similar way and I haven't read many complaints about the visual quality. --------------------------------------------------------------------- Please do not reply to this automatically generated notification from Issue Tracker.
