Fixed image drawing inconsistencies when drawing 1x1 images/subrects.
We special cased 1x1 source rects by calling fillRect() with a solid
color, but that produces slightly different rasterization leading to
gaps when drawing 9-patch images for example. This patch makes us only
use the optimized path for scaling transforms or simpler.
Task-number: QTBUG-10018
