Please add better visualization for running/crouching/prone state in RetroDays tileset

[x-qq]

Is your feature request related to a problem? Please describe.

Currently if you use UltiCa tileset, you get a visual indicator when the character is running/crouching/prone directly on the character icon (arrows in bottom right corner of the sprite).

However there is no such indicator in RetroDays tileset, and as a result it is very easy to forget that you are running, run out of stamina and receive 3 hours worth of pain (and die if it happened at a bad time).

Solution you would like.

Arrow indicators that are used in UltiCa would be an ideal solution, but if that's not possible any improvement at all is welcome.

Describe alternatives you have considered.

If the UltiCa-like arrow indicator is not possible, maybe character sprite could change its color.
Or have a couple of differently-colored pixels on the character sprite.

I think the lack of icon in Retrodays is there on purpose to keep the tileset simple. But 1) We could definitly add it to Neodays and 2) the move mode icons could go in the icon mod for Retrodays

[x-qq]

I think it would be reasonable for the base (i.e. unmodded) tileset to have this functionality, because it's an important aspect of the game and the tileset already implements visuaization of other similar state modifications like riding a mount.

I don't think RetroDays should have overlays without a mod. Riding a mount is simple and not an explicit overlay, the game makes it happen for free, and I think is quite a different class than the informational overlays most tilesets have.
