Primitive media dimension helpers.

These helpers keep width and height calculations explicit and validated.

Examples

use use_dimensions::{Dimensions, is_landscape, pixel_area};

let size = Dimensions::new(1920, 1080).unwrap();

assert_eq!(size.area(), 2_073_600);
assert!(size.is_landscape());
assert_eq!(pixel_area(1920, 1080).unwrap(), 2_073_600);
assert!(is_landscape(1920, 1080).unwrap());
