* Makefile.in (eval.o): Depend on dispextern.h.
* dispnew.c (buffer_posn_from_coords): Fix calculation of dy for
image glyph using image's ascent.
(mode_line_string): Return image glyph as object clicked on.
Adjust y0 for image glyph using image's ascent.
* dispextern.h (FACE_ID_BITS, MAX_FACE_ID): New defines.
(struct glyph): New members, ascent and descent. Used to save
this glyph's ascent and descent, instead of having.
(struct glyph): Declare member face_id using FACE_ID_BITS.
(find_hot_spot): Add prototype.
* keyboard.c (Qimage): Remove extern (now in lisp.h).
(QCmap): Declare extern.
(make_lispy_position): When position is inside image hot-spot,
use hot-spot element's id as posn element.
* lisp.h (IMAGEP): New macro to test for image object type.
(Qimage): Declare extern.
* macfns.c (Qimage): Remove extern (now in lisp.h).
(valid_image_p, parse_image_spec): Use IMAGEP macro.
* macterm.c (Qface, Qmouse_face): Remove unused externs.
* w32fns.c (Qimage): Remove extern (now in lisp.h).
(valid_image_p, parse_image_spec): Use IMAGEP macro.
* w32menu.c (Qmouse_click, Qevent_kind): Remove unused externs.
* w32term.c (Qface, Qmouse_face): Remove unused externs.
* xdisp.c (Qarrow, Qhand, Qtext, Qpointer): New variables for
pointer types.
(Qrelative_width, Qalign_to): Remove unused variables.
(Vvoid_text_area_pointer): Replace Vshow_text_cursor_in_void.
(QCmap, QCpointer, Qrect, Qcircle, Qpoly): New variables for
image maps.
(x_y_to_hpos_vpos): Return glyph relative coordinates through
new dx and dy args.
Remove buffer_only_p arg (always 0). Simplify code accordingly.
(get_glyph_string_clip_rect): Draw cursor using glyph's rather
than row's ascent and height, to get sensible height on tall rows.
(build_desired_tool_bar_string): Remove Qimage extern.
(get_tool_bar_item): Fix call to x_y_to_hpos_vpos.
(produce_image_glyph): Adjust it.ascent to minimum row ascent if
image glyph is alone on the last line.
(append_glyph, append_composite_glyph, produce_image_glyph)
(append_stretch_glyph): Set glyph's ascent and descent.
(on_hot_spot_p): New function to check if position is inside an
rectangular, circular, or polygon-shaped image hot-spot,
(find_hot_spot): New function to search for image hot-spot.
(Flookup_image_map): New defun to search for image hot-spot.
(define_frame_cursor1): New aux function to determine frame pointer.
(note_mode_line_or_margin_highlight, note_mouse_highlight):
Handle `pointer' text property and :pointer image property to
control frame pointer shape. Detect image hot-spots for pointer
and help_echo properties. Use define_frame_cursor1.
(note_mouse_highlight): Use Vvoid_text_area_pointer.
(syms_of_xdisp): Defsubr new defun. Intern and staticpro new variables.
DEFVAR_LISP Vvoid_text_area_pointer instead of Vshow_text_cursor_in_void.
* xfaces.c (cache_face): Abort if c->size exceeds MAX_FACE_ID.
* xfns.c (x_set_mouse_color): Remove bogus x_check_errors call.
(Qimage): Remove extern (now in lisp.h).
(valid_image_p, parse_image_spec): Use IMAGEP macro.
* xmenu.c (show_help_event): Remove unused code.
* xterm.c (Qface, Qmouse_face): Remove unused externs.
(x_draw_hollow_cursor): Draw cursor using glyph's rather than
row's ascent and descent, to get a sensible height on tall rows.
