+/**
+ Whether to apply a vertical gradient to the sides of a fill-extrusion layer. If
+ true, sides will be shaded slightly darker farther down.

+ The default value of this property is an expression that evaluates to `YES`.
+ Set this property to `nil` to reset it to the default value.
+
+ You can set this property to an expression containing any of the following:
+
+ * Constant Boolean values
+ * Predefined functions, including mathematical and string operators
+ * Conditional expressions
+ * Variable assignments and references to assigned variables
+ * Step functions applied to the `$zoomLevel` variable
+
+ This property does not support applying interpolation functions to the
+ `$zoomLevel` variable or applying interpolation or step functions to feature
+ attributes.
