Terrain brush question in isometric-staggered

[chenpangzi]

I use examples isometric_grass_and_water.tmx, the terrain brush work good,
but when i change orientation to staggered, the brush is working wrong!
see this image, missing 2 tiled.

First off, please decide where to post your question, be it on the forum or as a GitHub issue, rather than posting it in both places.

In any case, I believe this was working correctly at some point, but it evidently is broken now. I'll need to investigate what is going wrong here. Thanks for the report!

Well, I broke this in change 01944e9, which makes an assumption about neighbor proximity that is not valid for staggered maps. I think expanding the maximum area processed by one tile will fix this up.
