InfoWindow and anchor support for MarkerViews.

还没有人认领这个 Issue。

I've been playing with the MarkerView plugin so we can experiment with Lottie animations on our markers. While messing with em i've noticed that the plugin is in very early stages and doesn't have much support for anything.

I wasn't able to set an anchor on the view I supplied. So whenever it was added to the map the top left corner of the view was the lat/lng while the rest of the view was laid out below and to the right. I've made my own copies of the 2 classes in the plugin to adjust this.

The view also didn't seem to update its location frequently enough, zooming and panning the map would leave it in the same spot until the map was done rendering. I was able to get around this in my own version of the 2 classes as well.

I wasn't able to find a good way to hook the InfoWindow support the mapbox map has using marker views, is this something that will be added to this plugin? The same question goes for the other things i've had to adjust. Or would it be smarter to try and move to using symbol layers than waiting for this plugin to advance?

先检查 MarkerView 插件以及 issue 中提到的两个类，然后将其当前行为与 map 对 symbol-layer 和 InfoWindow 的支持进行比较。确认在平移和缩放期间 anchor 定位及更新时机的工作方式。确定 anchor、频繁的位置更新和 InfoWindow 支持的范围并达成一致后，即可视为完成。
