/*!
 QGCPalette is used in QML ui to expose color properties for the QGC palette. There are two
 separate palettes in QGC, light and dark. The light palette is for outdoor use and the dark
 palette is for indoor use. Each palette also has a set of different colors for enabled and
 disabled states.

 Usage:

        import QGroundControl.Palette 1.0

        Rectangle {
            anchors.fill:   parent
            color:          qgcPal.window

            QGCPalette { id: qgcPal: colorGroupEnabled: enabled }
        }
