 // This class is used to track occlusion of layers while traversing them in a front-to-back order. As each layer is visited, one of the
 // methods in this class is called to notify it about the current target surface.
 // Then, occlusion in the content space of the current layer may be queried, via methods such as occluded() and unoccludedContentRect().
-// If the current layer owns a RenderSurface, then occlusion on that RenderSurface may also be queried via surfaceOccluded() and surfaceUnoccludedContentRect().
+// If the current layer owns a RenderSurfaceImpl, then occlusion on that RenderSurfaceImpl may also be queried via surfaceOccluded() and surfaceUnoccludedContentRect().
 // Finally, once finished with the layer, occlusion behind the layer should be marked by calling markOccludedBehindLayer().
