FillTool

Paint-bucket tool for "fill" mode, reached via PixelArtCanvas.tools.fill.

export interface FillTool {
  global: boolean;
}

global

• false (default): floods the 4-connected region from the seed pixel.
• true: recolors every matching pixel on the canvas.

Runtime-only: no constructor option. Persists across mode switches.

IMPORTANT

A global fill commits as a single atomic edit and broadcasts a compact "global-fill" event ({ fromColor, toColor }) instead of "stroke". Undo/redo replays it as a full "stroke".
