--- Comment #1 from Fujii Hironori <Hironori.Fujii at sony.com> ---
In Image::drawTiled, this Image size was 640x435.
But, visibleSrcRect was 640.0x435.00031.

In Cairo::drawSurface, it create a subsurface by taking enclosingIntRect of srcRect.

> IntRect expandedSrcRect(enclosingIntRect(srcRect));

I guess expandedSrcRect would be 640x436.
