Captured view-transition snapshots need to be rescaled when the intrinsic size
of the image is
different to the layout size of the pseduo element.
The captured image covers the overflow rect of the original element, but the
border-box subset
defines the intrinsic size.
This computes the scale factors required to scale the intrinsic size of the up
the replaced
content size of the pseudo renderer. It then scales the overflow rect (in
coordinates of
the original element) into coordinates for the pseudo renderer.
Painting of the pseudo element (both new and old variants) are updated to
factor this
scale in to the draw commands or layer attributes.
Doing this sizing during painting correctly exposed bugs where the computed
layout of
the pseduo renderer was incorrect.
ViewTransition:::copyElementBaseProperties is changed to use the 'frameRect' of
the view
(instead of the 'contentsWidth') when computing the size of the root element,
so that
space taken up by scrollbars isn't removed.
RenderObject's calculation of the 'IsAnonymous' flag is changed so that the
view-transition
pseudo elements are not considered anonymous and then correctly can be
containing blocks
for their descendants.
