Cary Clark f5404bbcf4 update bookmaker
change https://skia-review.googlesource.com/c/skia/+/91380
should have triggered a bookmaker failure but, while
it reported the error it did not return that the check
failed. See
https://chromium-swarm.appspot.com/task?id=3adfe04df6f9ce10&refresh=10

Update bookmaker to detect and return error

also, add some SkImage examples
fixed some linefeeds
