  Revert "Round when scaling values"
  
  This reverts commit 10f964623f003c70f6bdd33423420abda3820ce0.
  
  See discussion with Khaled Hosny on mailing list.  In short, since
  integers here can be negative, and int division is "round towards
  zero", proper rounding should take sign into account.  Just skip
  doing it again, has been serving us well before.

• TODO

• General fixes:
  =============
  
  - AAT 'morx' implementation.
  
  - Return "safe-to-break" bit from shaping.
  
  - Implement 'rand' feature.
  
  - mask propagation? (when ligation, "or" the masks).
  
  - Warn at compile time (and runtime with HB_DEBUG?) if no Unicode / font
    funcs found / set.
  
  - Do proper rounding when scaling from font space?  May be a non-issue.
  
  - Misc features:
    * init/medi/fina/isol for non-cursive scripts
  
  
  API issues to fix before 1.0:
  ============================
  
  - API to accept a list of languages?
  
  - Add init_func to font_funcs.  Adjust ft.
  
  - hb-ft load_flags issues.
  
  - Add pkg-config files for glue codes (harfbuzz-glib, etc)
  
  - 'const' for getter APIs? (use mutable internally)
  
  - Remove hb_ot_shape_glyphs_closure()?
  
  
  API additions
  =============
  
  - Language to/from script.
  
  - blob_from_file?
  
  - Add hb-cairo glue
  
  - Add sanitize API (and a cached version, that saves result on blob user-data)
  
  - BCP 47 language handling / API (language_matches?)
  
  - Add hb_font_create_unscaled()?
  
  - Add query / enumeration API for aalt-like features?
  
  - SFNT api? get_num_faces? get_table_tags? (there's something in stash)
  
  - Add segmentation API
  
  - Add hb-fribidi glue?
  
  
  hb-view / hb-shape enhancements:
  ===============================
  
  - Add --width, --height, --auto-size, --ink-box, --align, etc?
  
  
  Tests to write:
  ==============
  
  - ot-layout enumeration API (needs font)
  
  - Finish test-shape.c, grep for TODO
  
  - Finish test-unicode.c, grep for TODO
  
  - GObject, FreeType, etc
  
  - hb_cache_t and relatives
  
  - hb_feature_to/from_string
  - hb_buffer_[sg]et_contents
