This is a modified version of tagcanvas with TagCanvas.Stop(id) added.
In TagCanvas, there's a TagCanvas.Start(id) interface. When in SAP applications, according to template reloading, it's common for a name to be assigned to several different element. When calling TagCanvas.Start() on the same name repeatedly, those after the first one will not entering drawing loop correctly.
So I added a TagCanvas.Stop(id) interface, you just need to call it before you call TagCanvas.Start(id), or just after route change.
