Enum SpriteFit 

pub enum SpriteFit {
    Fit,
    Cover,
    Bottom,
}

How a screen-owned overlay element (a Sprite, TextLabel, or HitRegion) maps from the 1280x720 reference canvas to the live window when their aspect ratios differ.

Screen-owned UI is authored against a fixed reference canvas and uniformly scaled to the window at runtime.

Variants

Fit

The canvas fits inside the window, centered, leaving margins on the shorter axis. UI elements keep their proportions and stay fully visible.

Cover

The canvas fills the window, centered, cropping the overflowing axis equally on both sides. Full-bleed stage imagery (scene backdrops, character portraits) reaches the window edges without distorting, and content anchored to a canvas edge stays flush with the window edge.

Bottom

The canvas keeps the fit scale (no cropping), but the whole overlay is shifted so the reference bottom edge lands on the window bottom edge. Bottom-anchored furniture (a visual-novel dialog box and its controls) hugs the window bottom at any aspect ratio instead of floating above a letterbox margin.
