Sort fields in ComputedStyleBase in decreasing order of size Sort fields in ComputedStyleBase in decreasing order of size. This is a micro optimization that improves field alignment and minimizes wasted memory space. From Intel on 'Coding for Performance': https://software.intel.com/en-us/articles/coding-for-performance-data-alignment-and-structures "One can try to minimize this memory wastage by ordering the structure elements such that the widest (largest) element comes first, followed by the second widest, and so on."
