Fix T96238: shrinking to zero doesn't actually scales the radius to zero 

Probably to prevent the radius of a point from being stuck at zero,
the `Shrink/Fatten` curve operator sets a minimum value of `0.001`
for all points being transformed.

This is an inconvenience as these points may have been purposely set
to zero on the panel.

And it also doesn't follow the convention seen in other operators
(which keep the value zero).

So remove this limitation.
