Do we need to convert the Y axis?

I'm on the way to resolve #39 .
But I found something weird.

Left Top should been 0,0

Yes, this cause bugs.


Since we are rendering from the bottom left, this will cause the sort order to be abnormal.

Ok, I found something in my old PR: StarArawn/bevy_ecs_tilemap#405.
It seems that bevy_ecs_tilemap does not support reversing the y-axis.
This means that even if I perform the correct calculations, I can’t get the texture to display correctly.
Or can we actually flip the y-axis ourselves?

Hey!
I just tried both your tiledtest_y_even and tiledtest_y_odd maps from #39 and I actually see the expected rendering. I don't understand what is the issue.
What's the problem with not having the same reference between Tiled and bevy_ecs_tilemap ?
If you really want, you could have some kind of translation function and convert from one reference to the other.

The map high will cause render bug.
You can change map high to odd/even to check render effect.
