for cc.rect in cocos2d/cocoa/CCGeometry.js

var a = cc.rect(0,0,30,30); // works
var b = cc.rect(a); // don’t works

I’m not sure but I think the bug is in cc.rect
cc.rect = function (x, y, w, h) {
return new cc.Rect(x,y,w,h); // cc.Rect has always 4 arguments passed and never see 0,1,2 or 3 arguments
};
