feature request: shadow behind letters of UIButton

[stefaniamak]

The request

A shadow to be added below the letters of a UIButton (not the whole button itself), similarly to the screenshot below:

Details

The feature should be something that the developer can turn "Frue" or "False" to their ui file, similarly how it is done here Terasology/LightAndShadow#141 .

You can use as reference the PR Terasology/Dialogs#18 , which was a first attempt on adding this feature in-game. In that closed PR, you can also see some of the concerns when adding that feature.

I'd think this a request for something like UiText, comparable to colored text or changing the type face. The described used case could be implemented using sucha rich text control as child of button, or turning the rich text control itself into a button that can be clicked...
