Knotted ribbon -#1 - PSP script

This neat script will take any ribbon of yours, and tie it in 5 places. You can use a full lenght ribbon or a shorter one. The script will determine if it has to reuse the same section repeatedly (in a small piece), or use the full lenght of a longer ribbon. All the knots will end up on a separate layer from the ribbon pieces in case you want to insert some decorations in the knot (a ring, a flower, etc.). You can use any ribbon you have, or a ribbon created by another script. This script will resize the ribbon correctly and if it is impossible to make a knot out of it, it will let you know.
