so this has been a definite consideration for some time. i thought that several terminals generate a sequence to notify the application of this, but maybe that's just something i imagined, or asked for? i'd need to go look.
if there's no sequence generated, ideally such a change would result in a SIGWINCH. upon receipt of a SIGWINCH, we query the screen dimensions, and could theoretically query the back/foreground then, eliminating the need to poll (i'm definitely not adding notcurses-level support for polling). i suppose i could expose the initial queries to the app for it to run in a loop, but i really, really dislike that idea.
let me look around see whether i'm just hallucinating about a sequence sent by the terminal. if i am, i'll consider adding this to SIGWINCH handling, but i'd probably hide it behind a non-default notcurses_init()
option. the big problem is that if we're going to blindly query these, we logically ought query the palette as well, which is a big nasty operation (O(n) on the size of the palette).

fwiw i'm using wezterm -- after a quick glance at the code, it doesn't seem like there's any special event being sent to the running program. I'm using window:set_config_overrides
to change the colour_scheme
via the lua api.

the idea of the app polling this really makes me want to vomit. let me look back over my emails; i know i wanted a solution to this problem.
