A lot of methods take |const EditorRawDOMPoint&| as their argument. However, some of them are called with EditorDOMPoint::AsRaw(). This is not good for performance because: 1. Needs to create temporary instance of EditorRawDOMPoint. 2. EditorRawDOMPoint::AsRaw() may be used by simple mistake. 3. Such methods may call EditorRawDOMPoint::Offset(), however, it's not copied to the original EditorDOMPoint instance. So, callers may need to compute offset again. So, such methods should be changed to template methods if they are not virtual method and AsRaw() should be gotten rid of for prevent it looking not expensive.
