That should also remove the need to display the bounding box all the time.
----------------------
The current plan is to do something similar to what do we for the existing curve objects.
If there is no radius in the curves, then draw the selected curves with the selected color:
{F13143375}
If, however, the curve has any radius, it should use the equivalent of its mesh representation:
{F13143385}
Note that this is similar to the old curve system that would use mesh for drawing any time that the curve had a surface:
{F13143378}
