Summary: @public ... and we initalize this in Surface. We need this for requesting images with proper size/pixel-density, setup proper parameters for rasterizing CALayer's and rounding layout metric values. Then we have to figure out how to wire this up with YGConfig. Reviewed By: fkgozali Differential Revision: D8475639 fbshipit-source-id: cec7af581b94efb4595dcf3f232252ce87a1fde3
