Layers physically move when being transferred to a new folder which has a different transform

[Keavon]

This requires some knowledge of linear algebra and transforms, for example by people who have experience with computer graphics or gamedev.

#2177 can be useful reference for how transforms are modified for cross-scope movement.

Hey @Keavon Is this still on ? I could take it if it's the case

[Keavon]

@lyingpasta go for it! This'll be valuable to solve.

@Keavon can you give some example of what it's intended for this behavior ? Do we need the transform property of the parent layer to be applied to all it's children or compute a new transform based on the original one and the parent's ?

[Keavon]

@lyingpasta For each layer that's dragged out of a certain folder, it should have a transform applied to it that puts it back into its original transformation as if the user had dragged it back there (and resized/scaled/skewed it). If multiple layers are dragged out of a certain folder, that applies individually to each one of them.

It seems like it's actually the case, I created 3 layers one of them with a scaling transform when I drag one layer to it, the transform applies to it also, then I drag it back out and it goes back to its original state. Isn't this what we need ?

[Keavon]

It needs to do exactly not that. Any layer rearranged in the layer panel should never change its transform within the canvas.
