Considering inheritance: Components, Sprites, Point2d+Vector

[g--o]

Basically using a paradigm of inheritance via:

function child_ctor(...) {
    parent_constructor.call(this, ...);

    // actual initiator
    this.init = function() { ... };

    //...

    this.init();
}

The problems considering this option are:

• Breaks the getComponent related methods somehow
• Different sprites want to override update/render while retaining parent's update/render as seperate method.
• For point2d: inherits methods that don't really apply to points as a concept like dot product
