Extra Color / Swatch Drag + Drop Support
This MR adds drag and drop support for color swatches in two specific circumstances:
- A color swatch (from the palette docker or FG / BG color selector) can be dragged onto the canvas to quickly fill a selection.
- A color swatch can be dragged onto the layerbox to quickly insert a fill layer, optionally using the current selection as a mask.
