[Feature request] Realtime

[jumpjack]

On my PC the processing of single small images (did you notice your tool also works fine with single images, if you "bypass" the file extension limitation in input? :-) ) is quite fast: could a "realtime checkbox" be added? The fisheye to equirectangular conversion of an image is driving me mad to find the right parameters...
I had to manually reduce the size of my 3000x2000 input image to 300x200 for fast processing: maybe the realtime checkbox could do it by itself once for all, and use thumbnail for subsequent processings.

This would be great. The same thing could be applied for videos. When a video is paused, it could take the current frame as an image and continuously apply the edited effect chain to it (when you change any values) so that you could find the right parameters. Often just seeing a single frame from a video is enough to determine if the effect is fine.
