Angle Double Parameters

Double parameters with their kOfxParamPropDoubleType property set to kOfxParamDoubleTypeAngle are interpretted as angles. The host could use some fancy angle widget in it's interface, representing degrees, angles mils whatever. However, the values returned to a plugin are always in degrees. Applicable to 1, 2 and 3D parameters.

For example a plugin that rotates an image in 3D would declare a 3D double parameter and flag that as an angle parameter and use the values as Euler angles for the rotation.
