A zoomable value which specifies the right padding between the shield and the text. The shield will automatically resize to include this padding.
You can specify the padding in either absolute terms (in pixels) or as a percentage of the overall shield width.
Examples:
shield-padding-right : 5
defines the right padding of the shield to be 5 pixels.
shield-padding-right : 5:5;10:20
defines the right padding of the shield to be 5 pixels on the zoom level 5 and 20 pixels on the zoom level 10.
shield-padding-right : 30%
defines the right padding of the shield to be 30% of the overall shield width.
