Dominik Röttsches 7d4e55c329 [sfnt] Improve paint limit checks
Paint tables can appear before the `base_glyphs_v1` offset if the
font is produced with the layer list before the base glyph list.  In
this case paint tables can occur after the layer list but before the
base glyph list.  Checks in the 'COLR' v1 code were rejecting fonts
with this layout.  Improve these checks by calculating a minimum
offset after which paint tables can occur and use that in safety
checks.

* src/sfnt/ttcolr.c (Colr, tt_face_load_colr): Declare
`paint_start_v1` and calculate that as the minimum of the end of
layer list and base glyph list.
(get_child_table_pointer, read_paint, tt_face_get_paint_layers):
Use that in safety checks.

README

FreeType 2.10.4
===============

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`.

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-2.10.4.tar.xz
  freetype-doc-2.10.4.tar.gz
  ftdoc2104.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

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'.
