Preview bug in all filter previews.

I small bug ois that the selected channels are ignored when makinf the preview.
- Try only select the red channel of an image and then apply a gausian blur

*The preview shows blur for all channels *The result is only on the red channel-

Somtimes I only want to blur a channel so the preview isnt correct in these situations.

Its obviously less processing to compute the plugin on less chanels so I think this should be added.

Note that the plug-in doesn't know about the fact that a channel is inactive. It's the core that keeps inactive channels from being changed so the computation is done on all channels. Your last statement isn't obvious; it's wrong even.

It would definitely be more complex to take the active components into account in the preview widget but it would not be impossible. If you open an enhancement request for it, someone might implement this feature one day.
