Since r76202 InsertMenuItem is used when adding checkable menu items even without a bitmap. The call fails because hbmpChecked and hbmpUnchecked are set to HBMMENU_CALLBACK on pre-Vista, making the menu owner drawn unnecessarily. Fix by adding GetHBitmapForMenuCheckable which is used when assigning values to hbmpChecked and hbmpUnchecked. GetHBitmapForMenu remains unchanged (for possible porting reasons) and is used for hBmpItem only. git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@76757 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
