-----------
Disable sorting of CALayers that aren't CATransformLayers.
https://bugs.webkit.org/show_bug.cgi?id=248292
rdar://problem/102634551>
Reviewed by Simon Fraser.
CoreAnimation currently sorts all layers by depth, and disabling sorting for a
layer also disables
sorting for any transform-layer children.
If supported, this disables sorting for all normal layers and re-enables it for
transform-layers,
so that only preserve-3d content is sorted (as specified by css-transforms-2).
This brings the CA rendering in line with other rendering backends, as well as
hit-testing/point-mapping.
This doesn't make any change if we can't enable sorting just for
transform-layers, but this isn't a regression,
as we already have a mismatch between rendering and hit-testing for that case.
One thing we could do in the future is disable sorting for layers that don't
have any transform-layer children,
and fix a subset of the bugs fixed by the full change here. Keeping track of
the child list adds complexity though,
and this is a long-standing bug, so that change isn't made here.
