Half the tile size so that Tiled maps can stay simple and compatible with existing libraries and frameworks, but allow the tools to apply RPG Maker stile automapping.Unfortunately, when we go this way then this kind of code would need to be added to all libraries and frameworks out there that support Tiled maps. Build into Tiled some intelligence about how to cut and recombine these autotiles.However, it is plain annoying to have to preprocess your tilesets and it needlessly increases the texture size. I'm not sure what's the best way to support it. In any case the question comes up a lot, I guess mainly because of the vast library of tilesets available alongside (or made for use with) RPG Maker. Outside of RPG Maker, the format used by Tiled is actually quite common.

It would definitely be interesting to support this type of terrain, though I have not seen it used outside of RPG Maker so I kind of disagree with the format being "quite common".
