Shadow, outline ... on font?

Now exist settings for widgets, that outline/shadow Label(widget) area and maybe this is sometimes used. But more flexible will be shodow on letters or for example visible parts. Good example is ARC with shadow.

Is somethink as this planned?

These need to be adding LVGL.
We are working on v9 where will have a better architecture to add these.

These are not planned for v9.0, but we can consider them for v9.x
