widget: fix Editor.CaretCoords when scrolled

Browse Source 
This commit fixes the position returned by Editor.CaretCoords
to account for the scroll position of the editor. Without this
change, the returned coordinates can easily overflow the boundaries
of the editor widget when it has been scrolled on either axis.
