vector.js node non-erasable bug.

Hi Karsten,

I have tried the vector.js non-erasable bug, with three files, trochoid.node,
trochoid2.node, and CP_Oriented spi-Curve Result2.nod, with equivalent results.

A few permutations of Run, Stop, Apply, Delete, (+/-Undo), and Close script, were tried,
and yield different results.

The Curve is always delete-able.

If the Vectors have Not been deleted prior to Apply, they will not be Delete-able.

If the vectors Have been deleted prior to Apply, after Apply, they will be restorable and Delete-able.


1. ReOpen MoI, Load trochoid2.nod, press Run, Delete-able.

2. ReOpen MoI, Load trochoid2.nod, press Run, Stop, Delete-able.

3. ReOpen MoI, Load trochoid2.nod, press Run, (+/- Stop), Apply, (+/- Close nod), Only the curve will delete, the vectors are Not_Delete-able.

3. ReOpen MoI, Load trochoid2.nod, press Run, Select All, Delete, (+/- Undo), Apply, Close the nod. Curve is present. Vectors are recoverable with Undo.

In Short, the vectors need to be deleted before Apply is pressed. (And after deletion, it is OK to UnDelete the vectors, before Apply is pressed.)

(The permutations got confusing.)

(Also wondering about when blue curve should show up in Styles?)
