README.md - Wrong tile coordinate in tilemap image example
I was browsing through the README.md file and I think I found a mistake in an image about how to use tilemap in the Graphics section.

See in following screenshot:

Shouldn't be the value I highlighted (1, 0) and not (0, 1) as it is currently? 

Maybe I'm wrong. If so, please ignore this issue, and sorry about that. 😅
