    Capabilities are used to determine a specific platform service's availability.

    \value ColorPickingFromScreen The platform natively supports color picking from screen.
    This capability indicates that the platform supports "opaque" color picking, where the
    platform implements a complete user experience for color picking and outputs a color.
    This is in contrast to the application implementing the color picking user experience
    (taking care of showing a cross hair, instructing the platform integration to obtain
    the color at a given pixel, etc.). The related service function is pickColor().
