From: Eskil Abrahamsen Blomfeldt Date: Wed, 4 Jul 2012 12:56:38 +0000 (+0200) Subject: Add option to use native rasterizer for SceneGraph text X-Git-Tag: upstream/5.2.1~1481 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=b0b4869440fc6e5af42797cbcaa64ec30238be73;p=platform%2Fupstream%2Fqtdeclarative.git Add option to use native rasterizer for SceneGraph text For old-style (desktop components) apps using QML 2 on regular density displays, distance field text will look out of place. We introduce an option to use the native rasterizer instead if you would rather have native look and feel than scalable text items.
