Please provide a predefined IupColorDlg() so that plugins may provide color selection abilities.

I'm not against some form of standardized dialogs for seemingly common things, like this. However, I also wonder how valuable an IUP implementation will actually be in the long run. Obviously we don't have any sort of timeline regarding the GUI API change, but any sort of pre-defined dialogs like this should also be something that are used in the default GUI -- not just something made for the sake of it. And VO has at least 2 different color selectors that I'm aware of.

I've even got an HSV Color Picker which works. I just haven't been able to get it to scale very well, along with the issues where it doesn't get garbage collected properly (it's dynamically generated).

What level of complexity do you think would make it worthwhile?
