42	layer transformation	Hiro Lynx		"which transformations are needed must be discussed.

potential transformations:
- rotation by multiples of 90°
- horizontal/vertical flip
- move layer
- resample / crop layer

potentially needed features:
- layer size independent from canvas size
- absolute layer position

at first it could be just a button to select the full current layer and float it so it can be transformed using the selection transformation actions."	enhancement	new	major
