Updated: qt5-svg 5.15.18-1 (test)

[Mark Geisert]

The following packages have been uploaded to the Cygwin distribution:

* libQt5Svg5-5.15.18-1
* libQt5Svg-devel-5.15.18-1
* qt5-svg-doc-5.15.18-1
* qt5-svg-examples-5.15.18-1

Qt is a cross-platform application framework for desktop and
embedded development. Qt enables programmers to create advanced GUI
applications once and deploy them to Windows, Mac OS X and Linux without
rewriting the source code. Companies using Qt can leverage software
investments made on one platform across many others.

This is a test release of what is expected to be the last Qt5 version
available from upstream.  Please report any discrepancies from earlier
Cygwin-available Qt5 packages to the main Cygwin mailing list.  If all seems
well, this version will probably be promoted from test in a couple weeks.
Enjoy,

PS: This updated qt5-svg is required for doxywizard and 'octave --gui'.
