155 However CDefViewBckgrndMenu is more or less an overengineering result, its code could really be part of the
156 CDefView. Given this, I think that abusing the interface here is not that bad since only CDefView is the ony
157 user of this class. Here we need to do two things to keep things as simple as possible.
158 First we want the menu part added by the shell folder to be the first to add so as to make as few id translations
159 as possible. Second, we want to add the default part of the background menu without shifted ids, so as
160 to let the CDefView fill some parts like filling the arrange modes or checking the view mode. In order
161 for that to work we need to save idCmdFirst because our caller will pass id offsets to InvokeCommand.
162 This makes it impossible to concatenate the CDefViewBckgrndMenu with other menus since it abuses IContextMenu
163 but as stated above, its sole user is CDefView and should really be that way. */
