Revision: 15947
http://projects.blender.org/plugins/scmsvn/viewcvs.php?view=rev&root=bf-blender&revision=15947
Author: jaguarandi

Log Message:
-----------
SimpleDeform modifications:
* Added "Lock axis" options on taper and strech/squash (suggested by ZanQdo)
* Better control of deform factor (suggested by ZanQdo)
* Added eModifierTypeFlag_AcceptsCVs (so it now accepts both curves and meshes)
