This is another incremental change towards using the new render pipeline descriptor throughout the entire stack. Creates blueprints for hashing with the new descriptor when provided before then converting it to the old format for the native backend creation. BUG: dawn:642 Change-Id: I1927b12fd02b2fedf25ef4428f07e339fa666715 Reviewed-on: https://dawn-review.googlesource.com/c/dawn/+/46541 Commit-Queue: Kai Ninomiya <kainino@chromium.org> Reviewed-by: Kai Ninomiya <kainino@chromium.org>
