uisource code
Why does Button need to implement IEventSystemHandler?
about UGUI source code inheritance relationship:
Selectable:IEventSystemHandler, ...
Button:Selectable,IEventSystemHandler,...
and other similar ui components:DropDown,Scrollbar,Slider,Toggle,InputField
I don't think IEventSystemHandler is necessary,Is it?
