Bug 1194837 - Don't use the inverse orientation matrix when computing the image space invalidate rect. r=seth, a=sylvestre The orientation matrix converts from decoded image space to oriented image space. The invalidation rect is in decoded image space. So we need to use the orientation matrix to convert it to oriented image space, not it's inverse.
