From f4f1b53b9646288d73979f8339a90fbbbcb9eedc Mon Sep 17 00:00:00 2001 From: Lars Knoll Date: Tue, 16 Aug 2011 16:38:56 +0200 Subject: Move printing into it's own library Create a libQtPrintSupport library that contains our current printing infrastructure. Long term this will get replaced with a libQtPrint, as the current architecture is not really maintainable.
