Subject: Suppport up to 27 mouse buttons from DirectFB Plugin.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Previous to this update, our plugin accepts only 3 moue buttons
(from DirectFB, to be translated into Qt::MouseButton values.)
This update changes our Plugin, so that it will successfully
translate up to 27 mouse button numbers. It is unclear, to the
author, which configurations of DirectFB on Linux might be
capable of actually sending high-numbered mouse button Events
to Qt. But, if/when a DirectFB configuration does so, this
change makes Qt ready to recognize and work with the button event.

Task-number: QTBUG-24335
