- update to 20221101:
* Bugfix - removed forgotten if-then code used with scaling tests.
Majority of users won't notice a difference since most FontForge
fonts are created in the +x,+y quadrant. Users that might see a
change/difference are users drawing only in the -x, -y quadrant.
* Enhanced libspiro to allow closed-loop spiros starting with '['
or 'a' by seeking the first available 'v', 'c', or 'o' as start,
which may be found later in the spiro curve. This was the least
modification needed to allow call-test10 or call-test11 to pass.
* Due to confusion created when ppedit was also re-licensed as MIT
APACHE and GPL2+, it's necessary to re-clarify libspiro is GPL3+.
In summary, GPL can include MIT code, MIT code cannot accept GPL.
Please note code not in ppedit like libspiro's java is GNU GPL2+.
Please note that libspiro's improvements or patches are also GPL.
* Thanks to orbea for bugfixes concerning linking and linker flags,
and removing .libs from linker path (some linkers don't like it).
* Added more commenting in spiroentrypoints.h to clarify functions.
* Reconfigured code to avoid exporting bezctx_intf.h since this is
supposed to be internal to libspiro and not for external calling.
* Also added https://gcc.gnu.org/wiki/Visibility to reduce exports.
* SPIRO_INTERNAL_BEZCTX and call-test21.c added for simpler method
of accessing libspiro for programs that only need the end result.
* Test added for 'a','h' to ensure points don't overlap, else exit.

* Bugfix for CVE-2019-19847 affecting {call-test14 to call-test19}.
* Fix a memory access bug/error created earlier by patch 2017oct28
Users using tagpoint libspiro20150702 are unaffected by this bug.
Users using tagpoint libspiro20190731 are recommended to upgrade.
Thanks to Frederic Cambus for calling attention to these faults.
* Add optional 'end knot' for open curves (useful for displaying).
* CRA Version also higher than so-bump 1.0.5 used on some distros;
this maybe of interest to distros that bumped an earlier version.
* Some garbage-in/garbage-out checks to verify we have 'ah' pairs,
and we don't start with ']', or end with '['. Add libspiro.3 man.
* Corrected set_di_to_x1y1() to use a constant bandwidth of 0.0005
* Code improvements and bug fixes for better tagged/spiro results.
* Several improvements added to further increase libspiro's speed.

* Scaling bug fixed. This allows libspiro to scale, and move spiro
paths, therefore allowing users and/or programs the ability of
using/making templates.
* Additional spiro controls 'anchor' and 'handle' added.
* Toggle switch ncq added, to allow further control of output results.

* Important bug fix issue #11 (missing file not included in 0v4).
* 2 Minor bug fixes caught on Coverity scan, free() and if c=3.
* Re-edit lib and tests to be more accommodating of older compilers.
* Verify libspiro output data is correct for test curves {0,1,2,4}.
