It is now possible to rotate with switcher active.
Doing so can mess up switchers application windows.
Activate switcher on a viewport with windows, then rotate to another viewport
with windows while switcher is active. Switcher correctly updates the window
count and titles in the switcher window, but the window images are from the
viewport that switcher was initiated from. Switch a few times then rotate back
to the initiating viewport, windows in switcher can be out of sequence. The
sequence can also get messed when doing this with initiate all.
Fixed in CVS.
