 // TODO(miu): Revisit code factoring of these structs.  There are a number of
 // common elements between them all, so it might be reasonable to only have one
 // or two structs; or, at least a common base class.
 
 // TODO(miu): Make sure all POD members are initialized by ctors.  Policy
 // decision: Reasonable defaults or use invalid placeholder values to expose
 // unset members?
 
 // TODO(miu): Provide IsValidConfig() functions?
 
 // TODO(miu): Throughout the code, there is a lot of copy-and-paste of the same
 // calculations based on these config values.  So, why don't we add methods to
 // these classes to centralize the logic?
