/**
|

|
|
* (This is Fabric-compatible RCTSurface implementation.)
|
||
|
|
*
|
||
|
|
* RCTSurface instance represents React Native-powered piece of a user interface
|
||
|
|
* which can be a full-screen app, separate modal view controller,
|
||
|
|
* or even small widget.
|
||
|
|
* It is called "Surface".
|
||
|
|
*
|
||
|
|
* The RCTSurface instance is completely thread-safe by design;
|
||
|
|
* it can be created on any thread, and any its method can be called from
|
||
|
|
* any thread (if the opposite is not mentioned explicitly).
|
||
|
|
*
|
||
|
|
* The primary goals of the RCTSurface are:
|
||
|
|
* * ability to measure and layout the surface in a thread-safe
|
||
|
|
* and synchronous manner;
|
||
|
|
* * ability to create a UIView instance on demand (later);
|
||
|
|
* * ability to communicate the current stage of the surface granularly.
