Emil Sjolander 1cd7363bea Pass the parent size to YGNodeCalculateLayout instead of the node size
Summary: The size of the node is already set on the node however there was no way to set the size of the parent to the root so that the root could use percentages. This change fixes this by making the width and height passed to calculate layout be the width and height of the hypothetical parent.
