Detailed Description

 Defines a color by Hue, Saturation, Value and Alpha

    Form name: hsva
    Slots:
       1. hue        (Number)  Set the hue component (0.0 to 360.0)
       2. saturation (Number)  Set the saturation component (0.0 to 1.0)
       3. value      (Number)  Set the value component (0.0 to 1.0)
       4. alpha      (Number)  Set the alpha component (0.0 to 1.0)

    Note:  The operators osg::Vec3*() and osg::Vec4*(), (inherited from LcColor)
           return a const pointer to the RGBA color vector and not the
           HSVA color vector.
