* BListItems now store the top offset of the frame within the parent BListView. * This allows binary searching the clicked item. * ItemFrame() is now a cheap call. * Fixed several bugs in the sorting code of BOutlineListView which lead to crashes of client applications. * Implemented previously unimplemented functions in BOutlineListView. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@24092 a95241bf-73f2-0310-859d-f6bbb57e9c96
