(w32_draw_fringe_bitmap): Extend fringe background to

Browse source 
scroll bar gap.
(x_scroll_bar_create): Set bar->fringe_extended_p.
(w32_set_vertical_scroll_bar): Put leftmost/rightmost scroll bars
on frame edge.  Check fringe background extension.  Don't clear
extended fringe background area.
