Overview of changes leading to 1.4.0

Thursday, January 5, 2017

• Merged "OpenType GX" branch which adds core of support for
  OpenType 1.8 Font Variations. To that extent, the relevant
  new API is:

New API:
hb_font_set_var_coords_normalized()

with supporting API:

New API:
HB_OT_LAYOUT_NO_VARIATIONS_INDEX
hb_ot_layout_table_find_feature_variations()
hb_ot_layout_feature_with_variations_get_lookups()
hb_shape_plan_create2()
hb_shape_plan_create_cached2()

Currently variations in GSUB/GPOS/GDEF are fully supported,
and no other tables are supported. In particular, fvar/avar
are NOT supported, hence the hb_font_set_var_coords_normalized()
taking normalized coordinates. API to take design coordinates
will be added in the future.

HVAR/VVAR/MVAR support will also be added to hb-ot-font in the
future.

• Fix regression in GDEF glyph class processing.
• Add decompositions for Chakma, Limbu, and Balinese in USE shaper.
• Misc fixes.
