Constant libnotcurses_sys::NCVISUAL_OPTION_CHILDPLANE

pub const NCVISUAL_OPTION_CHILDPLANE: u32 = crate::bindings::ffi::NCVISUAL_OPTION_CHILDPLANE; // 0x0000_0020u32

allows you to indicate that the n field of ncvisual_options refers not to the plane onto which you’d like to blit, but the parent of a new plane.

A plane will be created using the other parameters in the ncvisual_options, as a child of this parent. This means things like, say, vertically centering a sprixel relative to the standard plane can be done in one step.
