Fix regressions introduced by previous commit.

- Conditionally enable and disable event masks as needed when we detect
  the mouse entering/exiting the deskbar area. This is necessary because
  otherwise the app_server appears to eat mouse messages due to the ctrl+cmd+
  resize shortcut. Also change some conditionals slightly to better deal with
  differing combinations of autohide and/or autoraise.
