Any plan to support Non-alternate screen?

[lotabout]

Great work! (I think you should share your work in Rust forum)

So, my feature request here is the non-alternate screen(don't know the official name) support. It seems that termfest will send escape code smcup to enter Alternate screen mode on terminal.enter_ca.

There are cases where programs hopes to stay in current screen instead of a whole new screen. For example skim (a fuzzy searcher) has a --height option which will make it occupy only part of the current screen.

Disclaimer: currently skim uses termion as the TUI library, but it did not support buffering. Thus I'm seeking some alternative libraries.

Thanks!
