+        For scroll events (vertical and horizontal scroll axes), the
+        value parameter is the length of a vector along the specified
+        axis in a coordinate space identical to those of motion events,
+        representing a relative movement along the specified axis.
+
+        For devices that support movements non-parallel to axes multiple
+        axis events will be emitted.
+
+        When applicable, a client can transform its content relative to the
+        scroll distance.
