Per layer map and tile size properties (or at least support for sub-tiles)

[jasonsparc]

I think it would be more fine-grained to specify collision points if tiles can be further subdivided into smaller sub-tiles (specially if the sub-tiles are really small), in the same way as how games like Diablo 2 specify special tile flags, like collisions.

Here's a picture of what I mean:

A single tile like this subdivided into this

The example above is a 160x80 isometric tile from Diablo 2 which divides evenly to 32x16 tiles for a 5x5 subdivision.

The same can be done with an isometric map having 32x16 cell sizes with 160x80 tiles, but it would be very ugly editing them in the editor.

Here's another example from Diablo 2 of how they used it to define collision points and other stuff:

I think these would be a great feature for the next release.

And if possible, the editor would probably be more flexible if, instead of an option for sub-tiles division, it would allow a per-layer map size and tile size properties. But I guess that would mean big changes in the tmx format, and also making the map-tag attributes redundant.

Thanks for the screenshots showing Diablo as an example. The feature has been requested before and is already covered by #149, so I'll close this one.

Indeed it is not trivial to implement. Though sub-tile support could be a little bit easier than being fully flexible, I would still rather make things fully flexible.
