from Emacs frames, so that calls to GetClipBox in w32term.c
correctly report when part of a frame is visible (including
scrollbars, etc). This prevents repeated redrawing of frames when
only a scrollbar is visible.
(w32_wnd_proc): Add more frame information to debugging output.
help-echo for a string which doesn't have help-echo itself, use
get-char-property to obtain the help-echo from the string's buffer
(note_mouse_highlight) <mouse-face>: When on a string that doesn't
have mouse-face, look for mouse-face ``under'' the string for
mouse-face from an overlay.
(fast_find_position): Add parameter STOP. In the final row,
stop before glyphs having STOP as object. Don't consider
glyphs that are not from a buffer.
(syms_of_xdisp): Initialize them.
(handle_single_display_prop): Don't change point, bind `object',
`position', and `buffer-position' instead to the object having the
`display' property, position in the object and position in the
buffer.
strings background width so that multi-line mouse-face is drawn to
the right edge of the window.
(show_mouse_face): Set the row's mouse_face_p flag after drawing
glyphs.
determine character positions in strings, use chars_in_text
instead of strwidth.
(dump_glyph_row) [GLYPH_DEBUG]: Take a glyph row instead of
a matrix as parameter; this is easier to use from GDB.
there exist overlay strings with newlines at POS.
(text_outside_line_unchanged_p): Return 0 if changes start at
START and overlays exist at START. Likewise for END.
(try_window_id): Give up if init_to_row_end returns 0.
coding.type is coding_type_no_conversion or coding_type_raw_text,
use Fset_buffer_multibyte to make the buffer unibyte if REPLACE is
non-nil instead of just setting enable_multibyte_characters in the
buffer to nil.
(menu_face_changed_count): Variable removed.
(Finternal_set_lisp_face_attribute): Doc fix. If FRAME is t, set
the menu_face_changed_default flag, otherwise set the FRAME's
menu_face_changed_p flag if the `menu' face has been changed.
Prevent calling set_font_frame_param if FRAME is t.
(make_face_cache): Initialize cache's menu_face_changed_p
from menu_face_changed_default.
(realize_basic_faces): Look into the frame's face cache to
determine if the menu appearance needs updating.
