Changing the saturation of the color and not throw an exception 😊

[BUG] NullPointerException

I have a colour picker inside a dockable frame from DockingFrames. It starts off minimized and when it is shown the colour picker throws an NPE

[BUG] Illegal argument exception when color wheel is tiny

Describe the bug
When the component gets too small such as when the frame is resized, the color wheel disappears entirely. However, the selection handle/circle is still visible and creates an exception when you click on it.

Exception in thread "AWT-EventQueue-0" java.lang.IllegalArgumentException: The saturation value (-5.3851647) must be between [0,1]
	at com.bric.colorpicker.ColorPickerPanel.setHSB(ColorPickerPanel.java:460)
	at com.bric.colorpicker.ColorPickerPanel$ColorPickerMouseInputListener.mousePressed(ColorPickerPanel.java:682)

[REQUEST] Horizontal layout for controls

By default the controls and preview swatch are displayed to the right of the color wheel. I'd like to see more customization available by default, specifically an option to have all the modes displayed below the color wheel by default laid out horizontally rather than vertically. It would save a lot of time :)
