Image adjustScale(final BufferedImage bi, final JComponent component, final int insetX, final int insetY)
DOCUMENT ME!

final double scalex = (double) component.getWidth() / bi.getWidth();
final double scaley = (double) component.getHeight() / bi.getHeight();
final double scale = Math.min(scalex, scaley);
if (scale <= 1d) {
 return bi.getScaledInstance((int) (bi.getWidth() * scale) - insetX,
 (int) (bi.getHeight() * scale) - insetY, Image.SCALE_SMOOTH);
} else {
 return bi;
