Summary: This allows an unsupported component to be rendered as a "unimplemented view" for better visualization of which component is missing. It is off by default, but configurable in the component factory. For now, the layout simply follows regular <View />, which means the width/height etc is based on the react component styling. The side effect is that components with 0 height/width won't show up at all. Reviewed By: mdvacca Differential Revision: D14869656 fbshipit-source-id: f31e012fb7dc1c64fcc431ea5aa45079a23a618e
