ctx.moveTo(x, y);
          if (width === 0 || height === 0) {
            ctx.lineTo(xw, yh);
          } else {
            ctx.lineTo(xw, y);
            ctx.lineTo(xw, yh);
            ctx.lineTo(x, yh);
          }
          ctx.closePath();
          break;
        case OPS.moveTo:
          x = args[j++];
          y = args[j++];
          ctx.moveTo(x, y);
          break;

          ctx.bezierCurveTo(
