Merge commit 'bde0500' into from-current-dlreader

This duplicates the old commit titled "Merge branch 'vendor-toast' into
open-books-with-joined-accounts"

Changes from the original merge attempt:

- Kept the vendor usage of #pragma mark
- Left in the testing of objc_arc before calling autorelease.
- Autoresizing mask left on wrapperView
- Shadow code for wrapper view retained; our tweaks turn it off anyway
  by setting kDisplayShadow to NO.
- Kept as close to vendor spacing usage as possible. (Use git diff -w to
  see differences in spacing).

These changes were kept to prevent future merge conflicts with the
upstream.
