Attachment: Bug 1874842 - Avoid redundant transformed copies of Canvas2d path builder. r?aosmond

If a path builder is left in place after a drawing command, and then user then
sets up new transforms before beginning a new path, the old path will get spuriously
transformed every time the transform is changed, even though it will never be used.
We want to delay actually transforming the path until we need to read from it or
write to it.
