[Klug-general] gimp rotation sequence layers duplication

[jwmartnet .]

Hi,

Anyone know much about how the gimp does rotation? I started with a
small image < 500x500 px, and performed the following procedure:

1) duplicate layer
2) rotate new layer 15 degrees
3) duplicate rotated layer
4) repeat from step 2

So I've got around 21 layers now and with each layer the rotation is
taking longer and longer, about two minutes - on an i7-4790k @ 4ghz.

Yawn.

James.
