Anti-aliasing filter support?

[remussatala]

Perhaps it would not be hard to implement support for anti-aliasing filter. It's obviously a very good idea. Necessary in fact.

Somewhat related: there is also a topic about adding a scaling filter at the forum:

Although strictly speaking, a (postprocessing) scaling filter is not the same as anti-aliasing...

For anti-aliasing, one straightforward approach might be to manually edit the sprites, including adding partial translucency pixels to the edges of each animation frame manually.
See for example this post about manual anti-aliasing:

(I don't know if images with partial transparency would be properly loaded by SDLPoP at this time, though.)
