w32fns.c (Fx_show_tip): Call try_window with last argument
TRY_WINDOW_IGNORE_FONTS_CHANGE. Delete the TODO ifdef: problem
solved. Round up the tip height to an integral multiple of the
frame's line height. Add FRAME_COLUMN_WIDTH to the tip width.
w32fns.c (Fx_show_tip): Call try_window with last argument
TRY_WINDOW_IGNORE_FONTS_CHANGE. Delete the TODO ifdef: problem

(face_before_or_after_it_pos, next_element_from_string)
(next_element_from_c_string, produce_stretch_glyph): Remove unused

Disallow old-style backquotes inside new-style backquotes.
Don't count unquotes to figure out when we're "syntactically inside
but semantically outside of a backquote" any more.
Extend the restriction no-unescaped-commas-and-backquotes-in-symbols
to all contexts.
* src/dispextern.h (struct it): New member overlay_strings_charpos.
* src/xdisp.c (next_overlay_string, load_overlay_strings): Record the
charpos where we computed n_overlay_strings.
(next_overlay_string): Load overlay strings at recorded position,
