Subject: [PATCH] ENH: KernelTransform's PointSet should use minimal point data

This data is not used, so it is better to have a lighter-weight char,
instead of the heavier PointType there.
Having PointType there might also confuse someone into thinking that
point coordinates should be provided there, or might be retrieved from it.
