Currently, the size limit for continuous textures is 10, which is much smaller than the commonly used 16 and quite restrictive.
At least make it a power of 2, right?

Describe the solution you'd like

Increase the side length limit of continuous to 16. Only 16 is enough, it is a power of 2, and is also the side length of a block's texture or a chunk.

Why do you need such a long spanning texture? I feel like 10 blocks is already quite a lot and allows for variations and patterns spanning more than a single block.
I also don't really see a reason why the limit would need to be a power of 2.

The downside of increasing the limit is that larger textures will take up more space on the texture atlas. A max size continuous texture of 10 by 10 already takes up the same space as 100 normal textures.

Why do you need such a long spanning texture?

I'm adapting a mod in which several pattern textures use loops of length 16.

And as I said, it's the side length of a chunk.
