// 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?
