2008-06-30 Michael Natterer <mitch@imendio.com> Some unrelated cleanups found while reviewing the offscreen window patch: * gdk/gdkwindow.c: add missing Since: 2.14 to the redirection functions, fix some function header indentation, update documentation of redirect_to_drawable(). * gdk/x11/gdkwindow-x11.c * gdk/x11/gdkpixmap-x11.c: fix function header formatting/indentation. * gtk/gtkwidget.c: use I_() on "damage_event". svn path=/trunk/; revision=20708
