PATCH: [#13656] Bad rotation computing for manual rotation higher than 180
degrees
By Fabrice Tiercelin
This enables rotation angles of more than 180 degrees to result in the same
rotation applied to the object (the result used to be clamps between -180 - 180
of the initial rotation).
The patch had to be modified to deal with IPO keys properly
