level members. Change members in union `u'.
(GLYPH_EQUAL_P): Check also members face_id and padding_p.
(GLYPH_CHAR_AND_FACE_EQUAL_P): New macro.
(SET_CHAR_GLYPH): Adjusted for the change of struct glyph.
(CHAR_GLYPH_PADDING_P): Likewise.
(GLYPH_FROM_CHAR_GLYPH): Likewise. Always return -1 for multibyte
characters.
on character terminals:
* dispextern.h (FACE_TTY_DEFAULT_FG_COLOR)
(FACE_TTY_DEFAULT_BG_COLOR): New macros.
* xfaces.c (Qunspecified_fg, Qunspecified_bg): New variables.
(syms_of_xfaces): Initialize and staticpro them.
(tty_defined_color): If the color name is unspecified-fg or
unspecified-bg, return FACE_TTY_DEFAULT_FG_COLOR and
FACE_TTY_DEFAULT_BG_COLOR, respectively, as the pixel value.
(tty_color_name): If the color pixel value is either
FACE_TTY_DEFAULT_FG_COLOR or FACE_TTY_DEFAULT_BG_COLOR, return
Qunspecified_fg or Qunspecified_bg, respectively.
(Finternal_set_lisp_face_attribute): Allow values Qunspecified_fg
and Qunspecified_bg for foreground and background colors.
(realize_default_face): If the foreground and background colors
are not specified, default to Qunspecified_fg and Qunspecified_bg.
(realize_tty_face): By default, set the face colors to
FACE_TTY_DEFAULT_FG_COLOR and FACE_TTY_DEFAULT_BG_COLOR.
[MSDOS]: Handle FACE_TTY_DEFAULT_FG_COLOR and
FACE_TTY_DEFAULT_BG_COLOR when face colors are not defined.
Reverse the colors if the default colors were reversed.
* dispnew.c (init_display): Initialize the frame pixels of the
initial frame to FACE_TTY_DEFAULT_FG_COLOR and
FACE_TTY_DEFAULT_BG_COLOR.
* term.c (turn_on_face): If the default fore- and background
colors are reversed, enter inverse video mode. Don't send color
escape sequences for unspecified foreground and background colors.
(turn_off_face): Handle unspecified-fg and unspecified-bg colors.
* dosfns.c (unspecified_colors): New variable.
(msdos_stdcolor_idx): Handle unspecified-fg and unspecified-bg
color names, return FACE_TTY_DEFAULT_FG_COLOR and
FACE_TTY_DEFAULT_BG_COLOR, respectively.
(msdos_stdcolor_name): Handle FACE_TTY_DEFAULT_FG_COLOR and
FACE_TTY_DEFAULT_BG_COLOR, return Qunspecified_fg and
Qunspecified_bg, respectively.
* msdos.c (IT_set_face): Support FACE_TTY_DEFAULT_FG_COLOR and
FACE_TTY_DEFAULT_BG_COLOR as pixel values.
* faces.el (face-read-integer, read-face-attribute)
(color-defined-p, color-values): Allow color values unspecified-fg
and unspecified-bg, handle them as unspecified.
(struct glyph): Add new sub-structure cmp to the union `u'.
(enum display_element_type): New member IT_COMPOSITION.
(enum prop_idx): New member COMPOSITION_PROP_IDX.
(struct it): New members cmp_id, cmp_len.
from the computed faces (the combinations created by
compute_char_face), so that we don't waste global face id's.
* xterm.h (struct x_display): Replace the fields faces and n_faces
with fields param_faces, n_param_faces, computed_faces,
n_computed_faces, and size_computed_faces.
(FRAME_FACES, FRAME_N_FACES): Replaced by...
(FRAME_COMPUTED_FACES, FRAME_N_COMPUTED_FACES, FRAME_PARAM_FACES,
FRAME_N_PARAM_FACES): New macros.
* xfaces.c: Doc fixes.
(init_frame_faces): Call new_computed_face to create entries for
the default and mode line faces. Use the FRAME...PARAM_FACES
macros.
(free_frame_faces): Use the FRAME...PARAM_FACES and
FRAME...COMPUTED_FACES macros. Don't use the copy flag; all
parameter faces have real X resources, and all computed faces just
have copies. Free both the parameter and computed face arrays.
(new_computed_face): New function.
(intern_computed_face): Renamed from intern_frame_face; callers
changed. Call new_computed_face.
(ensure_face_ready, compute_char_face, compute_glyph_face): Use the
FRAME...PARAM_FACES macros.
(recompute_basic_faces): Use the FRAME...PARAM_FACES and
FRAME...COMPUTED_FACES macros. Produce the computed faces by
starting with the base faces and merging in the parameter faces.
(Fset_face_attribute_internal): Use the FRAME...PARAM_FACES
macros. Just call recompute_basic_faces if the default or mode
line faces have changed.
* xfns.c (Fx_list_fonts): Use the FRAME...PARAM_FACES macros.
* xterm.c (dumpglyphs): Use the FRAME...COMPUTED_FACES macros.
* dispextern.h (struct face): Remove the copy member. This is no
longer necessary; all computed faces are copies, and no parameter
faces are.
resource allocation.
* xfaces.c (free_frame_faces): Do free the first two faces; don't
free anything from a face that's a copy.
(intern_frame_face): Mark every face we intern as a copy; its
resources are actually a combination of the real faces.
(Fset_face_attribute_internal): No need to check if we're trying
to free one of the frame's GC's; they never enter into the
picture.
garbaged whenever it goes from invisible to visible.
* dispextern.h (frame_garbaged): Move extern declaration from here...
* frame.h (frame_garbaged): ... to here. The FRAME_SAMPLE_VISIBILITY
macro uses it now, and this seems to be just as modular. Make a
new page, just for this and message_buf_print.
(struct frame): Doc fix for the `visible' field.
* process.c: #include "frame.h" instead of "dispextern.h"; the
only thing we care about from it is the frame_garbaged
declaration.
* ymakefile: Note dependency change.
Removed elements `nruns' and `face_list'.
LINE_HEIGHT and LINE_WIDTH macros removed.
New struct face with associated typedef FACE declared, along with
accessing macros.
