class LayerHandle

Defined at line 29 of file ../../src/ui/scenic/lib/flatland/flatland2_state.h

A globally scoped layer handle which is used to refer to `LayerObject` within the Flatland

session implementation, as well as `UberStructLayer` within `UberStruct`; the latter is used to

create the flattened list of `ResolvedLayer` that is displayed each frame.

TODO(https://fxbug.dev/523371761): update docs when LayerObject and UberStructLayer have been

unified in step 135.

TODO(https://fxbug.dev/523371761): TransformHandle/LayerHandle should maybe both be structs, not

classes. And what's up with UberStruct being a struct not a class?
