Large resoluton issues (u16 integer overflow and rendering artefacts) about tui-rs

[fdehau]

First of all thank you for taking the time to look into this since I've overlooked this issue until now.

Regarding your first point while I think that solution (A) is an easier path for the fix, solution (B) appears to be more future proof.

Regarding percentages you are making a very good point and moving to floats for better precision is ok for me.

I'm also interested in your setup for testing those cases if you don't mind sharing.

The setup is me rescaling a console window way over what my screen is (and getting frustrated doing so). 2^16 is not that much. At work my console window is stretched across 2 HD screens, which is halfway there.

In order to properly test conditions like that a virtual terminal backend may come in handy.

This issue is a bit about too many things at once, so for now I'll play with the ideas here and then I may come up with some PRs. Otherwise - feel free to split it.

#92 "resolves" artefacts with backends over 2^16 characters.

Percentage remains unresolved (I may look into it but last time I tried to do something, it took me so long that meanwhile you implemented an equivalent :D).

That's great 👍. As you suggested earlier, I think promoting dimensions to u32 might be the next step to cover most use cases. In the meantime, thanks to your work, we have an elegant solution to this problem =).
