2. implemented colour/font support for wxTreeCtrl items 3. corrected a bug in wxListCtrl colour/font support code, the items should now be deleted ok 4. SetProcessAffinityMask() correction, wxThread::SetConcurrency() kind of works (difficult to test on a UP machine) 5. wxMimeType::EnumAllFileTypes() added, works (somewhat) under MSW 6. made default fonts under MSW 10 points and not 12 - this is the standard size git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@4849 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
