Growl展示/消失的方式、超时消失、自定义图标等功能增强

[my522cn]

1. 现在Growl只能从右到左滑入展示，从下到上消失。建议参考PPT中的动画增加展示和消失的动画效果，例如任意方向滑入、渐入渐出等。
2. 建议增加自定义超时展示，超时后消失Growl.Error(“xxx”, timeout: xxx)
3. 建议增加自定义图标

如下是一个比较好的参考： https://github.com/Federerer/Notifications.Wpf

I believe you can already set a custom icon. Unfortunately it has to be a Geometry which makes it impossible to show a multi colored icon for example or an image. It would be better if the icon uses a contentpresenter.

Hi 🖐, I am not sure, I understand correctly your request.

You can change some parameters of the Growl using the GrowlInfo class, see : https://github.com/HandyOrg/HandyControl/discussions/1062#discussioncomment-1757698

Of course some of the feature you ask cannot be available !
