I don’t know if this qualifies as a suggestion or a bugreport, but there is currently an odd sort of issue with the SDL tiles mode.
Specifically, the issue is that, bar pitch black darkness and obscured LOS, the SDL Tiles mode of Cataclysm does not visualize lighting like the ASCII/Curses mode does.
It’s best visible when comparing pure SDL ASCII (with a bitmap font), with an ASCII-alike tileset.

Notice the area inside the garage.
I’ve looked in the Cataclysm code, and it seems that the lighting is drawn in one pass, before the items, terrain, and everything else is drawn. This makes sense for opaque lighting tiles - boomered vision, pitch darkness, and obscured LOS. But for low-light conditions that are displayed as greyed symbols in SDL ASCII mode, wouldn’t it make more sense to draw the lighting tile as an overlay instead, like the “multiple items” highlight indicator - but after everything else is drawn, in a separate pass?
I can’t compile the latest experimentals on my own for now, or I would’ve tested if it’s even possible, but it doesn’t seem outside the realm of possibility, and it might add back some of the missing ambiance to the tiles mode view.
