1. the main function for item insertion is now DoInsertItems() which allows for much more efficient addition of many new items at once 2. the items client data management is done entirely in wxItemContainer itself, the derived classes don't have to distinguish between void and object client data 3. many fixes for sorted controls, in particular implemented wxCB_SORT support in wxGTK combobox git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@47730 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
