    \brief Allows specifying which color components should be written to the
    currently bound frame buffer.

    By default, the property for each color component (red, green, blue, alpha)
    is set to \c true which means they will be written to the frame buffer.
    Setting any of the color component to \c false will prevent it from being
    written into the frame buffer.
