Fix infinite loop due to FPU limitation

Browse Source 
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.
