Toolbar buttons do not render nicely

Toolbar buttons feel a bit small and toggle buttons do not have a nice look. Defaults should be more pleasing to the eye.

Here is the current toolbar:

And here is the corresponding test case:

		UIManager.setLookAndFeel(new FlatLightLaf());
		JFrame frame = new JFrame();
		frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		JPanel panel = new JPanel();
		JToolBar toolBar = new JToolBar();
		JToggleButton button1 = new JToggleButton(new FlatFileViewFloppyDriveIcon());
		button1.setSelected(true);
		toolBar.add(button1);
		JToggleButton button2 = new JToggleButton(new FlatFileViewComputerIcon());
		button2.setSelected(true);
		toolBar.add(button2);
		JToggleButton button3 = new JToggleButton(new FlatFileViewDirectoryIcon());
		button3.setSelected(true);
		toolBar.add(button3);
		JToggleButton button4 = new JToggleButton(new FlatFileViewHardDriveIcon());
		toolBar.add(button4);
		panel.add(toolBar);
		frame.getContentPane().add(panel);
		frame.setSize(400, 300);
		frame.setVisible(true);

Here is a difference between FlatLaf and Windows L&F:

I think a simple improvement would be for toolbar buttons to have a small empty border around them.

@smileatom I suggested either a border or empty border. I think empty border would go better with the idea of “flat”.

Here are the same screenshots without and with empty borders:

I think buttons are easier to identify, aim at, and it looks less like a gray caterpillar 🙂
