commit a411517faf624657aa58979f5463115115093309
Author: Alexander Gramiak <address@hidden>
Commit: Alexander Gramiak <address@hidden>

    Rename generic x_* identifiers
    
    * src/image.c: Rename x_* procedures to image_*.
    
    * src/frame.c: Rename x_* procedures to gui_*. Rename
    xrdb_get_resource to gui_display_get_resource. Rename x_get_arg to
    gui_display_get arg.
    
    * src/frame.h: Rename can_x_set_window_size to can_set_window_size.
    
    * src/xfaces.c: Rename realize_x_face to realize_gui_face. Rename
    x_supports_face_attributes_p to gui_supports_face_attributes_p.
    
    * src/keyboard.c:
    * src/lisp.h:
    * src/nsterm.m:
    * src/w32term.c:
    * src/xterm.c: Rename x_get_keysym_name to get_keysym_name.
    
    * src/nsfns.c:
    * src/nsterm.m: Rename x_* procedures to ns_*.
    
    * src/w32fns.c:
    * src/w32term.c: Rename x_* procedures to w32_*.
    
    * src/termhooks.h (query_colors, get_focus_frame, focus_frame_hook)
    (frame_visible_invisible_hook, iconify_frame_hook)
    (set_window_size_hook, set_frame_offset_hook, set_frame_alpha_hook)
    (set_new_font_hook, set_bitmap_icon_hook, implicit_set_name_hook)
    (activate_menubar_hook, change_tool_bar_height_hook)
    (set_scroll_bar_default_width_hook)
    (set_scroll_bar_default_height_hook, get_string_resource_hook): New
    terminal hooks to replace backend-specific x_* procedures.
    
    * src/dispextern.h (clear_under_internal_border): New RIF procedure.
    
    * src/alloc.c:
    * src/frame.c:
    * src/xdisp.c: Use FRAME_OUTPUT_DATA instead of FRAME_X_OUTPUT.
    
    * src/frame.c:
    * src/w32term.c:
    * src/w32fns.c: Use FRAME_NATIVE_WINDOW instead of FRAME_X_WINDOW.
