| /* A VectorDrawable is composed of a tree of nodes. |
| * Each node can be a group node, or a path. |
| * A group node can have groups or paths as children, but a path node has |
| * no children. |
| * One example can be: |
| * Root Group |
| * / | \ |
| * Group Path Group |
| * / \ | |
| * Path Path Path |
| * |
| * VectorDrawables are drawn into bitmap caches first, then the caches are drawn to the given |
| * canvas with root alpha applied. Two caches are maintained for VD, one in UI thread, the other in |
| * Render Thread. A generation id is used to keep track of changes in the vector drawable tree. |
| * Each cache has their own generation id to track whether they are up to date with the latest |
| * change in the tree. |
| * |
| * Any property change to the vector drawable coming from UI thread (such as bulk setters to update |
| * all the properties, and viewport change, etc.) are only modifying the staging properties. The |
| * staging properties will then be marked dirty and will be pushed over to render thread properties |
| * at sync point. If staging properties are not dirty at sync point, we sync backwards by updating |
| * staging properties with render thread properties to reflect the latest animation value. |
