Real tray icons transparency.
Patch by Owen Taylor <otaylor redhat com>
Fix bug #552953.
* Makefile.am:
* na-tray-child.[ch]: new files, to subclass GtkSocket, and have a
better life
* na-tray-manager.c: (na_tray_manager_plug_removed): trivial update
(na_tray_manager_make_socket_transparent): killed
(na_tray_manager_socket_exposed): killed
(na_tray_manager_socket_style_set): killed
(na_tray_manager_handle_dock_request): updated for NaTrayChild
(na_tray_manager_set_visual_property): set _NET_SYSTEM_TRAY_VISUAL
(na_tray_manager_manage_screen_x11): call
na_tray_manager_set_visual_property(), and some cleanups
(na_tray_manager_get_child_title): killed, replaced by a NaTrayChild
method
* na-tray-manager.h:
* na-tray.c: (tray_added), (tray_removed): don't force a redraw of the
icon. It shouldn't be needed anymore now, with NaTrayChild.
(na_tray_expose_icon): new, paint the icon if it's composited.
(na_tray_expose_box): updated to for na_tray_expose_icon()
(na_tray_init): connect to the expose event of the box
(idle_redraw_cb): updated to use na_tray_child_force_redraw()
(na_tray_force_redraw): remove a comment
* na-tray.h: remove NaTrayChild from there
* testtray.c: (tray_added_cb): update some code
