/* 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.
