-// - Paint rects (update rects): regions of a layer that needed to be re-uploaded to the
-//   texture resource; in most cases implying that they had to be repainted, too.
-//
-// - Property-changed rects: enclosing bounds of layers that cause changes to the screen
-//   even if the layer did not change internally. (For example, if the layer's opacity or
-//   position changes.)
-//
-// - Surface damage rects: the aggregate damage on a target surface that is caused by all
-//   layers and surfaces that contribute to it. This includes (1) paint rects, (2) property-
-//   changed rects, and (3) newly exposed areas.
-//
-// - Screen space rects: this is the region the contents occupy in screen space.
-//
-// - Replica screen space rects: this is the region the replica's contents occupy in screen space.
-//
-// - Occluding rects: these are the regions that contribute to the occluded region.
