Some unit fixups (#96335)
Fri Dec 20 11:59:22 2002 Owen Taylor <otaylor@redhat.com>
Some unit fixups (#96335)
* pango/pango-layout.c pango/pango-mapping.c:
Fix occurrences of "in thousandths of a device
unit" to say "in #PangoGlyphUnit" which will
give a link to the PangoGlyphUnit docs.
* docs/tmpl/text-attributes.sgml: Change 1000 to PANGO_SCALE.
* docs/tmpl/glyphs.sgml: Fix docs for PangoGlyphUnit,
fix mention of value of PANGO_SCALE from 1000 to 1024.
* pango/pango-layout.c (pango_layout_line_get_x_ranges):
Fix the docs for @ranges so it doesn't sound like the
coordinates are in pixels.
