- Date: Mon, 26 May 2014 07:27:32 +0000 (UTC)
commit 98d6f44231ed03f380c62f01cb3553385bb0d02d
Author: Michael Natterer <mitch gimp org>
Date: Mon May 26 09:23:55 2014 +0200
app: move GimpDial's background drawing to a new parent class, GimpCircle
so we can use that as a parent class for other circle/wheer interactions
in other subclasses.
