Grid control properties for childs should not be stored in Dictionary, it slows down the painting and resize

[generalloki]

Instead of static Dictionary<Control, int> controlColumns = new Dictionary<Control, int>(); static Dictionary<Control, int> controlRows = new Dictionary<Control, int>(); static Dictionary<Control, int> controlColumnSpans = new Dictionary<Control, int>(); static Dictionary<Control, int> controlRowSpans = new Dictionary<Control, int>(); static Dictionary<Control, bool> controlIsSharedSizeScopes = new Dictionary<Control, bool>(); we need to have in each Control custom named attributes and use them instead of these 5 dictionaries
