rect-native-css ported to C++ for performance. This is a prototype and not production ready. Ideally this eventually bereact-native-css@4.0.0

This library is a port ofreact-native-css to C++ for performance. It will eventually be a drop in replacement forreact-native-css and they will share the same compiler.

Unlikereact-native-css, the majority of the processing is done off thread in C++. When styles are updated they are directly applied to the Shadow Tree nodes.

There are two exceptions where styles are applied via a React re-render:

• A non-style prop is changed (e.gcaretColor)
• The component is animated (the component has a transition or animation style)

These are the features that are "done", in that they pass basic testing. More complex testing is needed to ensure they work in all cases.
