Subject: Revert "made setting rotation match Second Life" Second Life seems to
 have introduced a bug, as we have confirmation that SL behavior changed
 recently and changed in contradiction to their stated intention This appears
 to be another of the bugs SL is notorious for. Signpost and I have decided to
 back this out until SL's intention becomes clear.

This reverts commit f7b88d1c40ba06c62491d8d32809fe6c1c4d360d.
