2.5 / Nodes / Transformations
- after talking with Martin P (theeth), I have now shuffled code around
so that there is no more exception code for nodes in the wrong places.
This means node editor now also use entirely common translation.
As proof of concept, there is now also resize and rotate support. It already
works, but there need to be a bit more thought in how those
actions are initialised for node editor. Probably some way to tell
what to use as pivot point, etc.
