+ * VectorDrawableAtlas provides offscreen buffers used to draw VD and AnimatedVD.
+ * VectorDrawableAtlas can allocate a standalone surface or provide a subrect from a shared surface.
+ * VectorDrawableAtlas is owned by the CacheManager and weak pointers are kept by each
+ * VectorDrawable that is using it. VectorDrawableAtlas and its surface can be deleted at any time,
+ * except during a renderFrame call. VectorDrawable does not contain a pointer to atlas SkSurface
+ * nor any coordinates into the atlas, but instead holds a rectangle "id", which is resolved only
+ * when drawing. This design makes VectorDrawableAtlas free to move the data internally.
+ * At draw time a VectorDrawable may find, that its atlas has been deleted, which will make it
+ * draw in a standalone cache surface not part of an atlas. In this case VD won't use
+ * VectorDrawableAtlas until the next frame.
+ * VectorDrawableAtlas tries to fit VDs in the atlas SkSurface. If there is not enough space in
+ * the atlas, VectorDrawableAtlas creates a standalone surface for each VD.
+ * When a VectorDrawable is deleted, it invokes VectorDrawableAtlas::releaseEntry, which is keeping
+ * track of free spaces and allow to reuse the surface for another VD.
