        src            : w32term.c 

Log message:
        (remember_mouse_glyph): New function.
        (w32_mouse_position): Use it.
        (note_mouse_movement): If the mouse moved off the glyph, remember its
        new position.
        
        Sync with xterm.c:
        (notice_overwritten_cursor): Renamed from note_overwritten_text_cursor.
        Rewritten to take glyph widths into account.
        (x_y_to_hpos_vpos): Add parameter BUFFER_ONLY_P.
        (fast_find_string_pos): New function.
        (fast_find_position): Return the correct vpos.  Add parameter STOP.
        In the final row, stop before glyphs having STOP as object.
        Don't consider glyphs that are not from a buffer.
        (fast_find_position) [0]: Add a presumably more correct version for 
after 21.1.
        (expose_window_tree, expose_frame): Don't compute intersections here.
        (expose_window): Do it here instead.
        (expose_window_tree, expose_window, expose_line): Return 1 when
        overwriting mouse-face.
        (expose_window): If W is the window currently being updated, mark
        the frame garbaged.
        (expose_frame): If mouse-face was overwritten, redo it.
        (x_use_underline_position_properties): New variable.
        (syms_of_xterm): DEFVAR_BOOL it.
        (x_draw_glyph_string): Add comment to use it in future.
        (x_draw_glyph_string): Restore clipping after drawing box.
        Fix a computation of the underline position.
        (w32_get_glyph_string_clip_rect): Minor cleanup.
        (x_fill_stretch_glyph_string): Remove an assertion.
        (x_produce_glyphs): Don't convert multibyte characters
        to unibyte characters in unibyte buffers.
        (cursor_in_mouse_face_p): New function.
        (x_draw_stretch_glyph_string): Use it to choose a different GC
        when drawing a cursor within highlighted text.  Don't draw
        background again if it has already been drawn.
        (x_draw_glyph_string_box): Don't draw a full-width
        box just because the glyph row's full_width_p flag is set.
        (x_draw_glyphs): Fix computation of rightmost x for full-width rows.
        (x_dump_glyph_string): Put in #if GLYPH_DEBUG.
        (w32_draw_relief_rect): Extend left shadow to the bottom and left;
        change bottom shadow accordingly. Some cleanup.
        (x_update_window_end): Handle overwritten mouse face
        also for tool bar windows.
        (show_mouse_face): Set the glyph row's mouse_face_p flag also when
        DRAW is DRAW_IMAGE_RAISED.
        (clear_mouse_face): Return 1 if text with mouse face was
        actually redrawn.  Make the function static.  Reset
        dpyinfo->mouse_face_overlay otherwise note_mouse_highlight might
        optimize away highlighting if we pass over that same overlay again.
        (note_mouse_highlight): Call mouse_face_overlay_overlaps
        to detect a case where we have to highlight a different region
        despite not having left the currently highlighted region.
        Set mouse_face_overlay in the x_display_info.  Avoid changing the
        mouse pointer shape when show_mouse_face has already done it, or
        there is no need.  Handle mouse-face and help-echo in strings.
        (glyph_rect): New function.
        (w32_mouse_position): Use it to raise the threshold for mouse
        movement event generation.
        (w32_initialize_display_info): Initialize the x_display_info's
        mouse_face_overlay.
        (w32_set_vertical_scroll_bar): Don't clear a zero height or width area.
        (w32_set_vertical_scroll_bar, x_scroll_bar_create): Don't configure
        a widget to zero height.
