A whole lot of widening, refactoring, thinking, rethinking and fiddling around

for what ultimately boils down adding this method to BundledComponentRepository:

    @Override // from IMImageProvider
    public Mirage getTileImage (String path, Rectangle bounds, Colorization[] zations)
    {
        // we don't need our images prepared for screen rendering
        BufferedImage src = _imgr.getImage(getImageKey(path), zations);
        if (bounds != null) {
            src = src.getSubimage(bounds.x, bounds.y, bounds.width, bounds.height);
        }
        return new BufferedMirage(src);
    }

So much fun to revisit code I wrote six years ago.
