Fix minor bugs reported by the Coverity scan report.
* pango/opentype/harfbuzz-gdef.c (HB_GDEF_Build_ClassDefinition):
* pango/opentype/harfbuzz-gpos.c (HB_GPOS_Query_Scripts),
(HB_GPOS_Query_Languages), (HB_GPOS_Query_Features): Do not access
structs before we check them for nullity.
* pango/pango-layout.c (pango_layout_index_to_line),
(pango_layout_index_to_line_and_extents),
(pango_layout_index_to_pos): Check for invalid iterators outside the
loop, so we don't crash.
* pango/pango-layout.c (pango_layout_line_x_to_index): Set
char_trailing instead of trailing in one of too many paths. Should
have been a typo.
* pango/pangox.c (get_font_metrics_from_subfonts): Check for nullity
somewhere.
2006-04-03 Behdad Esfahbod <behdad@gnome.org>
* pango/opentype/harfbuzz-impl.h: Make sure TTAG_GDEF and frineds are
defined, needed for FreeType <= 2.1.7 (pointed by Tim Janik).
2006-03-31 Behdad Esfahbod <behdad@gnome.org>
Convert pango/opentype to the new project called HarfBuzz.

Protect against possible division by zeros (#316468, Steve Grubb)
* pango/pango-context.c (update_metrics_from_items),

offset is relative to the extension subtable, not the original
table. (Greg Aumann)

skip offsets that are zero. Works around bug in Doulos SIL Regular.
