doesn't have a buffer-local value in the current buffer, change
the global value by changing the value of the symbol bound in all
buffers not having their own value, to make it consistent with
what happens with other buffer-local variables.
(x_produce_glyphs): Don't xassert `it->descent > 0'; this isn't
true for images with `:ascent 100'.
(x_set_mouse_face_gc): If the last used mouse face has gone in the
meantime, use face MOUSE_FACE_ID.
If first glyph isn't a character glyph, use the ASCII NUL
character to determine the face.
(expose_area): Do not treat left margin specially.
(note_mode_line_highlight): If no local_map, check global keymap.
(note_mouse_highlight): Initialize overlay.
(clear_mouse_face): Don't return if tip_frame is non-nil.
(show_scroll_bars): Remove unused function.
(w32_read_socket) [WM_KILLFOCUS]: Set help_echo to Qnil.
(x_draw_bar_cursor): Remove extra test for out of bounds cursor.
Clip to row.
(x_erase_phys_cursor): Don't apply XWINDOW to variable that may be nil.
(x_free_frame_resources): Unload relief colors.
get_next_display_element when the newline is already found. This
may change the iterator's position, when its current position is
equal to the iterator's stop_charpos.
In the cache, use a key containing the information if scalable
fonts are included.
(x_load_font): Adapt to change of keys in the font cache.
(x_list_fonts): Ensure caching font information when
called for a null frame, which is the case frequently when Emacs
starts.
1 here rather than each time through
isearch-lazy-highlight-new-loop.
(isearch-lazy-highlight-max): Variable deleted.
(isearch-lazy-highlight-max-at-a-time): New user variable, like
isearch-lazy-highlight-max but controls a single invocation of
isearch-lazy-highlight-update.
(isearch-lazy-highlight-wrapped): Variable recreated.
(isearch-lazy-highlight-window-start): New variable.
(isearch-lazy-highlight-cleanup): Restored to behavior of
before 2-Jan.
(isearch-lazy-highlight-remove-overlays): Function deleted;
behavior folded into isearch-lazy-highlight-cleanup. "Keep"
behavior removed.
(isearch-lazy-highlight-new-loop): Restore old behavior of calling
isearch-lazy-highlight-update in a loop rather than just once.
Test isearch-invalid-regexp here and decide not to start a new
loop, rather than testing it each time through
isearch-lazy-highlight-update.
(isearch-lazy-highlight-search): Function restored.
(isearch-lazy-highlight-update): Get called in a timer loop again,
but this time highlight more than one match each time through.
Only highlight matches in the visible part of the window. Start
at point, move in the direction of the search, and wrap around at
the edge of the window. Use sit-for to force redisplay and ensure
window-start is credible. "Face suppressing" behavior removed;
overlay priorities should make it unnecessary, right?
(isearch-highlight): Face suppressing behavior removed.
(isearch-dehighlight): Face suppressing behavior removed.
(isearch-set-lazy-highlight-faces-at): Removed.
