### Issue description

TileSet->Setup->Separation maybe should have "px" like rest?

I know this is pixels from testing it.

TileSet->Select is this Animation Separation "px" too? idk

I tried setting up animation separation and got a not enough room error, so maybe not "px". idk


Thanks.


### Steps to reproduce

- open TileSet->Setup->Separation, note some have "px" and one doesn't
- open TileSet->Select, is this separation "px" too?
