Done.

 void Path::translate(const FloatSize& size)
 {
     m_path.offset(WebCoreFloatToSkScalar(size.width()), WebCoreFloatToSkScalar(size.height()));
 }

     return Op(m_path, other.m_path, kUnion_PathOp, &m_path);
 }
 
 #if !ASSERT_DISABLED
 bool ellipseIsRenderable(float startAngle, float endAngle)
 {

         || WebCoreFloatNearlyEqual(std::abs(endAngle - startAngle), 2 * piFloat);
 }
 #endif
