configfile >> "VScrollbar" doesn't exist either as far as I can tell
it's something like

class ScrollBar;
class RscControlsGroup {
	class VScrollbar: ScrollBar {

I tested just replacing line 19 with
class CA_IGUI_elements_group: RscControlsGroupNoScrollbars {
and and removing all scrollbar stuff and it works great because it is doing exactly the same thing

class RscControlsGroupNoScrollbars: RscControlsGroup {
	class VScrollbar: VScrollbar {
		width=0;
	};
	class HScrollbar: HScrollbar {
		height=0;
	};
};

Can you commit those changes directly, since you know exactly what else can be removed?
