Issue with scroll wheel

[iProgramMC]

I am working with the scroll wheel in proton and I've noticed a really weird issue and I tracked it down to FocusInputComponent::OnInput stupidly calling stuff with UpdatedVar. No, I don't need you to modify my precious scroll delta, it's not a position.

The original code:

void FocusInputComponent::OnInput(VariantList *pVList)
{
	//the 1 is because the pt we need modified is index 1 of the VariantList
	
#ifdef RT_FORCE_LEGACY_INPUT_HANDLING
	GetParent()->CallFunctionRecursivelyWithUpdatedVar("OnInput", pVList, string("pos2d"), 1, Entity::RECURSIVE_VAR_OP_SUBTRACTION_PLUS_ALIGNMENT_OFFSET);
#else
	//new way, which calls things in reverse order
	GetParent()->CallFunctionRecursivelyWithUpdatedVarBackwards("OnInput", pVList, string("pos2d"), 1, Entity::RECURSIVE_VAR_OP_SUBTRACTION_PLUS_ALIGNMENT_OFFSET);
#endif
}

My fixed(?) code (actually a hack, but you know):

void FocusInputComponent::OnInput(VariantList *pVList)
{
	//the 1 is because the pt we need modified is index 1 of the VariantList
	
#ifdef RT_FORCE_LEGACY_INPUT_HANDLING
	GetParent()->CallFunctionRecursivelyWithUpdatedVar("OnInput", pVList, string("pos2d"), 1, Entity::RECURSIVE_VAR_OP_SUBTRACTION_PLUS_ALIGNMENT_OFFSET);
#else
	//new way, which calls things in reverse order

	//HACK!!!!!!!!!!!!!!!!!!!!!!!!!
	if (int(pVList->Get(0).GetFloat()) == MESSAGE_TYPE_GUI_MOUSEWHEEL)
	{
		//TODO: just don't update the var.
		pVList->Get(5).Set(CL_Vec2f());
		GetParent()->CallFunctionRecursivelyWithUpdatedVarBackwards("OnInput", pVList, string("pos2d"), 5, Entity::RECURSIVE_VAR_OP_SUBTRACTION_PLUS_ALIGNMENT_OFFSET);
	}
	else
	{
		GetParent()->CallFunctionRecursivelyWithUpdatedVarBackwards("OnInput", pVList, string("pos2d"), 1, Entity::RECURSIVE_VAR_OP_SUBTRACTION_PLUS_ALIGNMENT_OFFSET);
	}

#endif
}

Really, there should be a CallFunctionRecursivelyBackwards instead.

This was no issue in Growtopia, because the thing that handles input isn't affected by alignment/position changes. My game was, though.
