- Fixed a bug in MakeCurveParametric that the curve does not always reach the specified max parameter.
- Added a new idl method MakeCurvePrametricNew that takes a number of steps as input instead of a step value (to achieve the fix and a more usual interface)
- Wrapped the new idl method in python MakeCurveParametric with a flag theNewMethod = true
- Modified the associated dialog in order to use the new method and dump it
