(oops I think I changed the title of another bug I was gonna file and hit submit before I realized ��)

While working on <https://webkit.org/b/230648>, I noticed that `DisplayList::Recorder::getCTM` never seems to include the device scale, meaning that if I try to use `ImageBuffer::compatibleBufferSize` and then `GraphicsContext::drawConsumingImageBuffer` it'll result in a blurry image (since the device scale used for the `ImageBuffer` is just `1`).
