XYDrawableAnnotation modification

[hugues]

I would have been hapy the be able to modify x, y of a XYDrawableAnnotation (and whyn not height and Width).
But it is not possible.

In my application I can make 3D animation of a mecanical model (function of time).
I also have functions depending on the time.
The goal is to have a annotation moving on my functions while the 3D animation runs.

I can do it with a ValueMarker.

I use for the same purpose a XYPointerAnnotation. It works fine.
An improvement would be to be able to select a background color for the text, and to be able to set a transparency coefficient on this background.
Regards.
