+         This config must be set unless:
+         1. {@link Configuration#isScreenRound} is true which means the display shape is circular
+            and the system will auto-generate a circular shape.
+         2. The display has no rounded corner and the system will auto-generate a rectangular shape.
+         (@see DisplayShape#createDefaultDisplayShape)
+
+         Note: If the display supports multiple resolutions, please define the path config based on
+         the highest resolution so that it can be scaled correctly in each resolution. -->
