Parameter Groups and Icons

Group parameters are typically displayed in a hierarchical manner on many applications, with 'twirlies' to open and close the group. The new property kOfxParamPropGroupOpen is used to specify if a group parameter should be initially open or closed.

Some applications are able to display icons instead of text when labelling parameters. The new property, kOfxPropIcon , specifies an SVG file and/or a PNG file to use as an icon in such host applications.
