Edge case where moving layers between groups changes the location, rotation or scale on the canvas

[timon-schelling]

Individual layers have their transforms set relative to parent node transforms. When such layer is moved outside of the parent into a different location in the nodegraph it changes its position on the canvas. It is really frustrating to work around this mechanic, and I believe many people will have similar opinion, especially those that come from other 2D apps.

Two solutions that might work here:

• make every layer have its transforms as absolute values relative to canvas origin (0,0)
• recalculate transforms when the layer is moved into a different place in the nodegraph so it's location, rotation and scale does not change

Reproduction:

Layer group needs to be transformed in some way - moved, scaled or rotated. When new layer is inserted the transforms are applied to it as well. With editor.graphite.rs:
