(#includes): Allow compilation with only Xaw.
(xaw3d_arrow_scroll, xaw3d_pick_top): New variables. (xt_action_hook): Replace XAW3D by XAW. (xaw3d_jump_callback): Renamed to xaw_jump_callback. (xaw_jump_callback): Renamed from xaw3d_jump_callback. Determine epsilon dynamically and don't try to be too clever. (xaw3d_scroll_callback): Renamed to xaw_scroll_callback. (xaw_scroll_callback): Renamed from xaw3d_scroll_callback. Handle both Xaw3d with arrow-scrollbars and with Xaw-style scrollbar (using `ratio'). (x_create_toolkit_scroll_bar): Try to detect which style of Xaw3d scrollbar we have so as to set it up more optimally and to fix xaw3d_arrow_scroll and xaw3d_pick_top. (x_set_toolkit_scroll_bar_thumb): Try to maintain 2 spare pixels at the bottom of the Xaw3d scrollbar, to work around its tendency to refuse shrinking the thumb. Also make sure that `XawScrollbarSetThumb' is not ignored, using a major gross hack. (x_initialize): Init default values for xaw3d_arrow_scroll and xaw3d_pick_top.
