Without the element-type they will be getting garbage, at least with
Python.

Apparently they are not (advertised as?) safe on BSD systems.
We ignore the case of static libraries.

Whitelisted on glibc, Android, and MSVC / mingw.

Simplifies hb_in_range() calls as the type can be inferred.
The rest is obsessiveness, I admit.

HB_VERSION_CHECK's comparison was originally written wrongly
by mistake.  When API tests were written, they were also written
wrongly to pass given the wrong implementation... Sigh.

Given the purpose of this API, there's no point in fixing it
without renaming it.  As such, rename.

API changes:

  HB_VERSION_CHECK -> HB_VERSION_ATLEAST
  hb_version_check -> hb_version_atleast

Bug 77800 - cppcheck reports

...to avoid an unused function warning; see mozilla bug https://bugzilla.mozilla.org/show_bug.cgi?id=984081.

Fix use-after-end-of-scope.

Let me know if this breaks anyone's anything.

The Myanmar shaper now respects the uniscribe-bug-compatibility
option too.

We are not using it for anything lse it seems.

Another static-initialization down.  One more to go.

Removes one more static-initialization.  A few more to go.

This changes all the HB_DIRECTION_* enum member values, but is
nicer, in preparation for making hb_segment_properties_t public.

This is the most convenient way to browse scripts.

Cross-checked with Mark Davis's spreadsheet at http://goo.gl/x9ilM

Can be -1 for NUL-terminated string.  This is useful for passing parts
of a larger string to a function without having to copy or modify the
string first.

Affected functions:

	hb_tag_t hb_tag_from_string()
	hb_direction_from_string()
	hb_language_from_string()
	hb_script_from_string()

We need this to set data on objects safely without worrying that some
other thread unsets it by setting it at the same time.

Where causing issues for people with MSVC.

The test/object test is passing again, instead of deadlocking.

It uses locale information to detect default language.  It's used by
hb_shape() whenever language is not set on the buffer.

Not sure how to properly test it in the test suite.  Tested by observing
that with DejaVu Sans we select the proper local glyph version for U+431
under Serbian locale.  See http://www.pango.org/ScriptGallery

Step version up to 0.5.0.

Also, fix to pass "make distcheck"

For now, by taking a global user_data mutex.
