Convert log_clusters[] use from char offsets to byte offset - should make
Mon Mar 6 20:55:32 2000 Owen Taylor <otaylor@redhat.com>
* libpango/mapping.c example/viewer.c:
* modules/hangul/hangul.c modules/basic/basic.c modules/tamil/tamil.c:
Convert log_clusters[] use from char offsets to byte offset - should
make it easier to have all interface deal with stuff in byte offsets.
* libpango/mapping.c libpango/pango-glyph.h: Rename x_to_cp and cp_to_x
to make them "member functions" of glyph_string.
* libpango/pango-types.h: Add a rectangle type for use in storing
glyph/glyph-string extents, plus macros for extracting ascent/descent.
* libpango/fonts.c libpango/pango-font.h libpango/pangox.c: Virtualize
glyph extents function into the font.
* libpango/pangox.c modules/*/*.c examples/viewer.c: Convert over to
new rationalized unit system - everything in 1000ths of a point
or 1000ths of a glyph unit.
* libpango/pango-glyph.h libpango/glyphstring.c: Add function to get
extents of a glyph string. (We may want to fastpath the width in
the future, since getting the width seems to be a very common
and time-critical operation)
