Enhancement request, even more because APNG is an unofficial extension to the PNG standard. With regard to battery life I dislike the idea of supporting this. 4.2008.30-2 ships libpng12-0 1.2.8rel-1osso5 so this requires manual backporting and a LOT of testing first.
You can always stop animations on screen block. Or even put a checkbox on the wallpaper setting window (Show animated). The merge shouldn't be too intrusive as this is another format ans (if you want) another file extension (apng). Ovbiously I'm not talking a full motion pictue as background, but a sutil glow variation of something would be neat.

Sigh, I should set enhancement too when I write that. And as I said: This is not standardized at all. Let's see what we can do...
> Put it in a tablet as the background. Desktop background? Uh... That gets composited with Task Navigator and Statusbar, their icons, any of the enabled applets, Home menu text etc. This might be reasonable in Image viewer, but not in Desktop (imagine that and large RSS applet together, *Shudder*)... > You can always stop animations on screen block. It should stop also whenever it's not visible.
Setting HIGH visibility for exposure.
This is a good proposal for http://maemo.org/community/brainstorm/ . Please create a new entry there if you or someone wants to push for it. The problem is that you want animated backgrounds in the desktop. Animated PNGs is one potential solution but there might be more. Resolving this enhancement request as INVALID since it's the best option available, not because the request is invalid per se,
