Colour fill on Line Art Detection misaligned when different layer size/location used
GIMP version: 2.10.12-3 Operating System: Linux Package: Arch Linux latest [extra] repo
When the line art source layer's top left corner does not align with the active layer, the colour fill ends up offset by the difference. Reproducible by creating a basic line art layer, creating a layer above it as active, selecting "Source: layer below/above the active one", and moving the active layer. The resulting fills will offset the direction and amount the layer is moved. Also problematic when using a cropped layer as active.
Using "Source: All visible layers" does not have this issue, but does not allow the user to re-fill a section at will, as the fill can interfere with the line art detection.
