[Po Lu]

branch: master
commit dfee2790549df4be0fa841a00faafb50c9347f30
Author: Po Lu <luangruo@yahoo.com>
Commit: Po Lu <luangruo@yahoo.com>

    Fix default registry of Haiku font backend
    
    * src/haiku_support.h (struct haiku_zoom_event): Fix coding
    style.
    (enum haiku_font_specification): Move FSPECs over here.
    * src/haikufont.c (haikufont_apply_registry)
    (haikufont_get_fallback_entity, haikufont_pattern_to_entity)
    (haikufont_spec_or_entity_to_pattern, haikufont_list): Use
    `iso10646-1' as the default registry instead of `utf8', which is
    not a registry.
