| // 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. |
