Log Message:
-----------
View transition old snapshots incorrectly get scaled to the border-box size.
https://bugs.webkit.org/show_bug.cgi?id=269954
<rdar://123478049>
Reviewed by Tim Nguyen.
Drawing of the old snapshot rescales the image to the border-box size, even if
we captured a larger area.
We shouldn't apply scaling, just align the origin of the border-box in the
snapshot
to the border-box origin of the pseudo element.
This records the overflow rect for which the snapshot is captured, and uses it
to adjust the overflow rect of the pseudo element and align the painting
position of the snapshot.
As a slight cleanup, merges the two createRendererIfNeeded lambdas into a single
static function.
