Ben Wagner 15afb55458 [base] Report used stream's external status.
In `open_face` the initial stream is set on the face, along with the
information about if FreeType is the owner of the stream object itself.  The
loaders may in the course of their work replace this stream with a new
stream (as is the case for 'woff' and 'woff2'), which may have a different
ownership than the initial stream object (likely the original stream object
is owned by the user and is external, while the new stream object is created
internally to FreeType and is internal).  When the stream is replaced, the
face's flags are updated with the new ownership status.

However, `open_face` cannot itself free this stream as its caller
`ft_open_face_internal` is responsible for this.  In addition, in the case
of an error `open_face` cannot return an actual face with the new stream and
its ownership status to the caller.  As a result, it must pass this
information back to the caller as a sort of "failed face" so that the caller
can clean up.

`open_face` was already passing back the new stream but was not passing back
the stream ownership information.  As a result the stream may not have been
free'd when needed.

README

FreeType 2.12.1
===============

Homepage: https://www.freetype.org

FreeType is a freely available software library to render fonts.

It  is  written  in  C,   designed  to  be  small,  efficient,  highly
customizable,  and portable  while capable  of producing  high-quality
output (glyph images) of most vector and bitmap font formats.

Please   read  the   `docs/CHANGES`   file,   it  contains   IMPORTANT
INFORMATION.

Read the files `docs/INSTALL*`  for installation instructions; see the
file `docs/LICENSE.TXT` for the available licenses.

For using FreeType's git repository  instead of a distribution bundle,
please read file  `README.git`.  Note that you have  to actually clone
the repository; using a snapshot will  not work (in other words, don't
use gitlab's 'Download' button).

The FreeType 2 API reference is located in directory `docs/reference`;
use the file  `index.html` as the top entry point.   [Please note that
currently  the search  function  for  locally installed  documentation
doesn't work due to cross-site scripting issues.]

Additional documentation is  available as a separate  package from our
sites.  Go to

  https://download.savannah.gnu.org/releases/freetype/

and download one of the following files.

  freetype-doc-2.12.1.tar.xz
  freetype-doc-2.12.1.tar.gz
  ftdoc2121.zip

Mailing Lists
-------------

The preferred  way of  communication with the  FreeType team  is using
e-mail lists.

  general use and discussion:      freetype@nongnu.org
  engine internals, porting, etc.: freetype-devel@nongnu.org
  announcements:                   freetype-announce@nongnu.org
  git repository tracker:          freetype-commit@nongnu.org

The lists are moderated; see

  https://www.freetype.org/contact.html

how to subscribe.


Bugs
----

Please submit bug reports at

  https://gitlab.freedesktop.org/freetype/freetype/-/issues

Alternatively,    you    might    report    bugs    by    e-mail    to
`freetype-devel@nongnu.org`.    Don't  forget   to  send   a  detailed
explanation of the problem -- there  is nothing worse than receiving a
terse message that only says 'it doesn't work'.


Patches
-------

For larger changes please provide merge requests at

  https://gitlab.freedesktop.org/freetype/freetype/-/merge_requests

Alternatively, you can send patches to the `freetype-devel@nongnu.org`
mailing list  -- and thank you  in advance for your  work on improving
FreeType!

Details on the process can be found here:
