[ros-users] pcl inconsistencies

There seems to be an inconsistency in PCL (at least in cturtle...I haven't
checked latest), in that some methods take angles in radians and some in
degrees. For example, SACSegmentation::setEpsAngle() accepts degrees for
SACMODEL_ORIENTED_PLANE, but radians for SACMODEL_ORIENTED_LINE. Perhaps there
should be a single convention throughout PCL to avoid confusion? It's already
caused some headaches around here =)
