LayoutShadowNode

open class LayoutShadowNode : ReactShadowNodeImpl

Supply setters for base view layout properties such as width, height, flex properties, borders, etc.

Checking for isVirtual everywhere is a hack to get around the fact that some virtual nodes still have layout properties set on them in JS: for example, a component that returns a may or may not be embedded in a parent text. There are better solutions that should probably be explored, namely using the VirtualText class in JS and setting the correct set of validAttributes
