Trait rsvg::float_eq_cairo::FixedEqCairo

pub trait FixedEqCairo {
    // Required method
    fn fixed_eq_cairo(&self, other: &Self) -> bool;
}

Implements a method to check whether two f64 numbers would have the same fixed-point representation in Cairo.

This generally means that the absolute difference between them, when taken as floating-point numbers, is less than the smallest representable fraction that Cairo can represent in fixed-point.

Implementation detail: Cairo fixed-point numbers use 24 bits for the integral part, and 8 bits for the fractional part. That is, the smallest fraction they can represent is 1/256.
