From ac4af55972291db96cc6bfa322dc7d35b67f7775 Mon Sep 17 00:00:00 2001 From: Eskil Abrahamsen Blomfeldt Date: Mon, 2 May 2011 10:06:44 +0200 Subject: [PATCH] Make pixel size a qreal in QRawFont The pixel size in the font engines is already a floating point value. For maximum flexibility, we should expose this in the public API.
