Unity's Quaternion showed eulerAngles beside x/y/z/w, Rect about eleven rows
over four values, and Bounds center/extents/size/min/max: settable properties
alias the fields they wrap. A struct with public fields now shows only those; a
struct without shows its settable properties, so record structs and CultMath
matrices (properties over private rows) still get clean rows and vectors show
fields only.
