1. horz scrolling (not perfect yet) 2. more actions (clipboard, double click) 3. wxCaret fixes 4. clipboard support 5. wxTE_PASSWORD support wxScrolledWindow/wxlistBox: better hit test calculation: take into account GetClientAreaOrigin() fix for wxGTK bug in wxDC::Blit() in wxWindow::ScrollWindow draw transparent radio bitmaps under GTK wxWindow::ScrollWindow() can now scroll a part of window only git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/branches/wxUNIVERSAL@8404 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
