Werner Lemberg a3dd6d99a4 Fix multiple calls of `FT_Bitmap_Convert'. 
The documentation of `FT_Bitmap_Convert' says that multiple calls do
proper reallocation of the target FT_Bitmap object.  However, this
failed for the sequence

  non-empty bitmap
  empty bitmap
  non-empty bitmap

Reason was that `FT_Bitmap_Convert' only reallocated the bitmap
buffer if it became too small; it didn't make the buffer smaller.
For an empty bitmap following a non-empty one, only the buffer
dimension got set to zero, without deallocation.  If the next call
was a non-empty buffer again, an assertion in `ft_mem_qrealloc' was
triggered.

* src/base/ftbitmap.c (FT_Bitmap_Convert): Always reallocate target
buffer to the correct size.

* docs/CHANGES: Document it.

README 

  FreeType 2.8
  ============

  Homepage: http://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.

  The FreeType 2 API reference is located in `docs/reference'; use the
  file   `ft2-toc.html'   as   the   top  entry   point.    Additional
  documentation is available as a separate package from our sites.  Go
  to

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

  and download one of the following files.

    freetype-doc-2.8.tar.bz2
    freetype-doc-2.8.tar.gz

  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

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

  how to subscribe.


  Bugs
  ====

  Please submit bug reports at

    https://savannah.nongnu.org/bugs/?group=freetype

  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'.


  Enjoy!


    The FreeType Team
