// randy: we might wanna remove the f by default, similar to the Vector2 ?
// I know that we'll have a Range2i at some point, so maybe it's better to be explicit for less confusion?
// I'll leave this decision up to u charlie just delete this whenever u see it

// charlie: 
// Is this range stuff really necessary?
// Why not just:
// typedef Vector2 Range1f;
// typedef Vector4 Range2f;
// Vector4 also already have alias for x1, y1, x2, y2 and we could add an alias for min & max vectors (see linmath.c)
// This feels like introducing unnecessary complexity and vocabulary when it's really just
// another way to say Vector2 and Vector4.
