Finally fix this embarrassing bug. The fix is a kludge, but it will
be redone for 1.28 (harfbuzz-ng) anyway.

* pango/pangofc-fontmap.h:
* pango/pangofc-private.h:
Change PangoFc font loading API such that PangoContext is not passed
down. We use a new opaque struct called PangoFcFontKey. This struct
is in fact our font hash key. This avoids problems where previously
we were using context members that were not necessarily considered
by the pangofc layer when caching.
This is in preparation for lazy loading of fonts in the pangofc fontmap.

* pango/pango-types.h: Move PANGO_UNITS_ROUND here...
* pango/pangofc-private.h: ...from here.
* pango/pango-gravity.c: Document that pango_gravity_to_rotation()
returns angle in radians but pango_matrix_rotate() takes degrees.
* pango/pango-layout.c (pango_layout_run_get_extents):
* pango/pango-renderer.c (pango_renderer_draw_layout_line):
Retain metrics hinting when centering baseline (used for Latin, etc
in vertical mode).
* pango/pangocairo-fcfont.c (pango_cairo_fc_font_get_metrics),
(pango_cairo_fc_font_glyph_extents_cache_init): Respect metrics
hinting setting when moving glyphs around for vertical writing.
* pango/pangocairo-fcfont.c (_pango_cairo_fc_font_new): Apply
the gravity rotation before the pattern's matrix, such that
vertical text gets correct italic direction.
* pango/pangocairo-font.c (_pango_cairo_font_get_hex_box_info):
Make hexbox font inherit most properties from the current font.
That is, bold hexbox digits for a bold font, etc.

* pango/pango-ot-buffer.c (apply_gpos_ltr), (apply_gpos_rtl),
(pango_ot_buffer_output):
* pango/pango-types.h:
* pango/pangofc-font.c (pango_fc_font_kern_glyphs):
* pango/pangofc-private.h:
Quantize kerning adjustment, otherwise all the metrics hinting
effort will be ruined by a non-whole-pixel kerning value.
In the future we want to take lsb_delta and rsb_delta into the
game before quantizing the adjustment here, but we don't have
those values handy right now.

Support per-item gravity.
* pango/pango-context.c (update_attr_iterator),
(itemize_state_init), (itemize_state_update_for_new_run),
(itemize_state_process_run): Make per-item gravity work, by setting
gravity into font description before loading fonts. Also, allow
the context font description to override the gravity (but not
centered_baseline.)
* pango/pangocairo-fcfont.c (_pango_cairo_fc_font_new): Get gravity
from font description, not context.
* pango/pangofc-fontmap.c (fontset_hash_key_equal),
(fontset_hash_key_hash), (fontset_hash_key_copy),
(pango_fc_make_pattern), (pango_fc_font_map_get_patterns),
(pango_fc_font_map_load_fontset),
(pango_fc_font_description_from_pattern): Get gravity from font
description, not context. Moreover, put it into pattern, and
reconstruct it out of font patterns.
* pango/pangofc-private.h: Define PANGO_FC_GRAVITY, which is the key
we put PangoGravity into an FcPattern under.

2005-11-22 Federico Mena Quintero <federico@ximian.com>
Fixes #322174:
* pango/pangofc-font.h (struct _PangoFcFont): Replace the
"gpointer context_key" field with "gpointer priv". This way we
can access the private data quickly, instead of using
g_type_instance_get_private().
* pango/pangofc-private.h: Added prototypes for
_pango_fc_font_{get,set}_context_key().
* pango/pangofc-font.c (struct _PangoFcFontPrivate): Moved the
"context_key" field to here.
(PANGO_FC_FONT_GET_PRIVATE): Use the "priv" field instead of GType
private data.
(pango_fc_font_class_init): Don't register GType private data.
(pango_fc_font_init): Initialize the private data here.
(pango_fc_font_finalize): Free the private data.
(_pango_fc_font_get_context_key): Implement.
(_pango_fc_font_set_context_key): Implement.
(pango_fc_font_get_glyph): Remove the g_return_val_if_fail(); it
was appearing quite high in the profile.
* pango/pangofc-fontmap.c (pango_fc_font_map_add): Call
_pango_fc_font_set_context_key() instead of setting the
fcfont->context_key directly.
(_pango_fc_font_map_remove): Likewise; also use
_pango_fc_font_get_context_key() instead of accessing the field
directly.

* pango/pangofc-font.c (pango_fc_font_create_metrics_for_context)
pango/pangofc-private.h pango/pangocairo-fcfcont.c: Cut out the meat of
pango_fc_font_get_metrics_for_context() and export it (privately),
so that PangoCairoFcFont can create a variant that sets the font
options on the context it creates. (#311522)

pango/pangocairo-fc.h: Start of a Cairo/FreeType backend.
* pango/pangofc-fontmap.[ch]: Add a "get_render_key"
virtual function to allow subclasses to specialize the
details of how caching works. Add a default implementation
that's a little more sophisticated than what was there
before.

Move default implementations of has_char(), get_glyph()
to the base class.
* pango/pangofc-private.h pango/pangoft2-private.h:

it is used by PangoXft.

* pango/pangofc-font.[ch]: Add hinted/transform flags
to the font structure to allow efficient conditionalization
of behavior rather than repeatedly extracting the information
from the FcPattern.
* pango/pangofc-font.c pango/pangofc-private.h pango/pangoft2.c:
Move the glyph metrics computation into a
_pango_fc_font_get_raw_extents() function that can be
shared with the Xft backend.
* pango/pangoxft.c: When a transform is in effect, don't
get glyph extents from Xft ... they are device space
and not useful, use _pango_fc_font_get_raw_extents() instead.
