Display color selection

When using color areas, it's important to clearly display the color selection in real time. This can be in a color swatch, directly on the canvas, or both.

Color loupe on down/touch states

The color loupe component can be used above the handle to show the selected color that would otherwise be covered by a mouse, stylus, or finger on the down/touch state. This can be customized to appear only on finger-input, or always appear regardless of input type.
