--- Comment #6 from Zalan Bujtas <zalan at apple.com> ---
With certain (big enough)values, the following code fails   

FloatRect rect(big number, big number, big number, big number);
FloatQuad quad(rect);
assert(rect.size() == quad.size())

because FloatQuad stores top left bottom right values internally -> float approx. value -> rect.m_size != quad.FloatRect(left, top, right - left, bottom - top).m_size
