The transform-node is a combination of all three transform types (translation, rotation and scale).
To make it resolution independent I added the "Relative"-Option as within the Translation-Node.
This is a very long outstanding code review, but still think it is useful to have.
If you don't want to work on this patch I can take over.
Use an enumeration
Better use a flag that is more descriptive.
Thanks for reviewing this patch. It has been a long time since i wrote this. But I exactly stuck to the code that is already there in the source code (translate note).
But if you'd wish to, I will take a look at it. I have to read into the source code again, since I am new to Blender development.
