Add a new attribute for scaling a font; also required adding
2000-11-01 Havoc Pennington <hp@pobox.com>
* pango/pango-attributes.c (pango_attr_scale_new): Add a new
attribute for scaling a font; also required adding PangoAttrFloat.
(pango_attr_iterator_get_font): Add PANGO_ATTR_SCALE handling.
* pango/pango-utils.c (pango_parse_stretch): Take a plain string
not a GString
(pango_parse_weight): ditto
(pango_parse_variant): ditto
(pango_parse_style): ditto
* pango/pangox-fontmap.c (pango_x_font_map_read_alias_file): pass
GString::str instead of the GString itself to pango_parse_*
* pango/pangoft2-fontmap.c (pango_ft2_insert_face): ditto
* pango/pangowin32-fontmap.c
(pango_win32_font_map_read_alias_file): ditto
* pango/pango-layout.c (get_tab_pos): adapt to new pango_itemize()
signature
(pango_layout_check_lines): Raise attr list copy/creation out of
the loop over paragraphs. Adapt to pango_itemize() changes.
* pango/pango-context.c (pango_itemize): pass in a starting
index and a cached iterator
(add_engines): Easy optimization, pass in
n_chars instead of recomputing it. Also, pass on the start
index and cached iterator.
* docs/pango-sections.txt: Add new stuff
docs/pango_markup.sgml: Docs on markup format
* pango/pango-layout.c (pango_layout_get_attributes): New function
to retrieve the AttrList from a layout
(pango_layout_set_markup): Set layout from markup
(pango_layout_set_markup_with_accel): Set layout from markup
including accelerator parsing.
* pango/pango-attributes.h (pango_parse_markup): New function to
convert a tag string to an attribute list
* pango/pango-markup.c (pango_parse_markup): implement
* docs/Makefile.am, docs/pango-docs.sgml, docs/pango-sections.txt,
docs/pango_markup.sgml: oooooh, documentation for the above patch!
* docs/tmpl/pango-unused.sgml: Remove from CVS; just causes
problems, and was full of checked-in conflict markers.
