Implement a grid debug overlay.

[phrohdoh]

Example:

[goto-bus-stop]

Could also be implemented as a utility that adds the grid lines to the terrain graphics, but a debug option would be nice to have so it works for any terrain.

Adding grid lines to the terrain tile PNGs won't work due to blending.

(thinks for a second)

OK it might actually work.

Still implementing it as a toggle-able shader is by far superiour IMO (think three-state spacebar: blending, no blending, blending with grid lines).

it looks like roller coaster tycoon :D

+1 for the shader. I have also listed a grid as a requirement for the final editor (see /doc/editor/terrain.md)

[franciscod]

it looks cool and everything, but where's the debug part?

[mic-e]

Uhm... I guess it's sort of easier to see whether buildings are correctly aligned, pathfinding works correctly, and stuff.

poor man's overlay terrain:
