5.0的漏斗图无效

文档关于interval的shape可以设定为funnel，但是无效。

看源码发现只有Funnel的坐标计算

G2/src/shape/interval/color.ts

Lines 40 to 68 in d481921

	if (!isPolar(coordinate) && !isHelix(coordinate)) {
	const tpShape = !!isTranspose(coordinate);
	const [p0, , p2] = tpShape ? reorder(points) : points;
	const [x, y] = p0;
	const [width, height] = sub(p2, p0);
	// Deal with width or height is negative.
	const absX = width > 0 ? x : x + width;
	const absY = height > 0 ? y : y + height;
	const absWidth = Math.abs(width);
	const absHeight = Math.abs(height);
	const finalX = absX + insetLeft;
	const finalY = absY + insetTop;
	const finalWidth = absWidth - (insetLeft + insetRight);
	const finalHeight = absHeight - (insetTop + insetBottom);
	return select(new Rect({}))
	.style('x', finalX)
	.style('y', finalY)
	.style('width', finalWidth)
	.style('height', finalHeight)
	.style('radius', [
	radiusTopLeft,
	radiusTopRight,
	radiusBottomRight,
	radiusBottomLeft,
	])
	.call(applyStyle, rest)
	.node();

color.tx 中却使用了Rect 绘制。funnel类型绘制什么可以支持？

嗯嗯，这里应该是一个 bug，color 没有消费 funnelPoints 这个参数，这里应该由 path 绘制才对。
