A new method called astNormPointsastNormPoints has been added to the FrameFrame
class. This is similar to the existing astNormastNorm method in that it can be
used to normalise axis values, but can be used on a vector of points rather
than just a single point. In addition, it has an option to choose a
normalisation that avoids discontinuities in the Frame's coordinate
system. The most common usage will be to modify vectors of sky position
in such a way as to avoid sudden jumps of 360 degrees in longitude within
groups of points that span the longitude origin.
- The mesh of points returned by astGetRegionMeshastGetRegionMesh and astShowMeshastShowMesh are now
normalised to avoid discontinuities in celestial longitude. This uses the
new astNormPoints methid described in the previous item.
