Where did the polygon, draw, sketch, and width tools go?
They are disabled by default due to problems. Instead of the polygon tool, you should use the bline tool. Instead of the width tool, you should just modify the width ducks directly. The draw tool was never completed, is very buggy, and frustrating to use. Since the draw tool is being disabled, then we might as well disable the sketch tool too. You can re-enable them without recompiling by setting some environment variables (you can set environment variables on windows too). Set SYNFIG_ENABLE_POLYGON, SYNFIG_ENABLE_DRAW, SYNFIG_ENABLE_SKETCH and SYNFIG_ENABLE_WIDTH to 1.
