The best plan would be to read the section of the layer shown in the preview
at 1:1 to a temporary paint device, filter that, and use toQImage to put it on
the display. No need for KisImage's here, of course, unless we want to show 
the effect of the filter on the layer in context. But I don't think that's 
necessary. Oh, and we should apply the selection as an alpha mask before 
filtering. The QImage can then be scaled to suit the preferences.
