Subject: [PATCH] Fix infinite loop due to FPU limitation
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

Bug detected with animatedtiles in example/animation.
In qpa mode, using some specific resolution of directfb such as
800x600 causes a bug in FillRectF where there is an infinite loop due
to scalabilty of qreal value: One is rounded and the other not.
