Is fvwm double buffered or not?

There was some discussion of this issue here:

eliminating flicker in FvwnButtons and icons

I was curious if there is a way to eliminate flicker in various places in Fvwm, specifically FvwmButtons and icons. Flicker occurs in a few places, for instance: My clock is powered by a FvwmScript that is updated every minute, that is swallowed inside a FvwmButton. Everytime it updates you can see a very quick flicker. I have an image that sits inside a FvwmButton. I have it set so if I click on an area on my desktop this image will slide into view. The image slides in very clean, but…

So no, no double buffering AFAIK.
