padLayer property
Specify a 📚 SurfaceLayer as 🔛 padLayer to receive Surface.padding value.
By default, passed entirely to 📚 SurfaceLayer.CHILD, but
optionally may be given to a 🔪 _clip within 📚 SurfaceLayer.MATERIAL
before rendering 👶 child.
The effect with 🔛 padLayer = 📚 SurfaceLayer.MATERIAL can be neat
with non-negligible Surface.padding as it adds a third customizable
📚 Layer to a 🌟 Surface.
- Consider 👓 Filter.filteredLayers
=👓 Filter.TRILAYER.
❗ Special Case
Specifying 📚 SurfaceLayer.BASE is a special case in which
Surface.padding is then split between 📚 MATERIAL and 📚 CHILD layers.
Implementation
final SurfaceLayer padLayer;
