Add ScreenOverlay support

Is there any coding standard for this? Would it be enough to (more or less) follow the structure of GroundOverlay class?

I do not know if this is used anymore now that google earth is dead. Is there any other client that uses this?

@cleder, that's a point. I see two main possibilities:

1. The purist approach: consider that KML, being an OGC standard, "deserves" a canonical implementation, disregarding the existence or not of applications actually using the full set of elements;
2. The pragmatic approach: given the constraints (time, effort, personal involvement), it would be much better to implement other, more useful features before "wasting time" with the underused ScreenOverlay element.

As such, the question follows: is there any other obvious condidate Element to implement next, instead of ScreenOverlay?

CesiumJs uses the gx extensions like flyTo, etc

Nice!

As a curiosity, since Marble is configured in this machine to open KML by
default, I could notice that currently it doesn't implement screen
overlay.

See ya!
