-												Content disappears on CSS parallax example

<rdar://problem/61997636>

Reviewed by Darin Adler.

If scrolling affects the computation of coverage rect of a TiledBacking, we plumb
that expanded coverage back into TransformState which is maintained during GraphicsLayer flushing,
and it's used to compute coverage rect for descendants.

It's passed into TransformState::setLastPlanarSecondaryQuad(), which has to map it back into
the coordinate system of the last flattening ancestor. However, TransformState::mapQuad()
had a missing return and the quad mapping was wrong. The new code is now the same as
TransformState::mappedPoint() (you can see where the copy/paste error came from).

-												The perspective matrix is affected by overflow:hidden on a box with borders
https://bugs.webkit.org/show_bug.cgi?id=211828

Reviewed by Zalan Bujtas.

Source/WebCore:

For a box with non-uniform borders, the layer created for overflow:hidden is not
centered in its parent layer. However, we push the childrenTransform onto this
clipping layer, so that transform needs to be adjusted to account for the geometry
of the clipping layer.
