Function validate_scale_factor

pub fn validate_scale_factor(scale_factor: f64) -> bool
Expand description

Checks that the scale factor is a normal positive f64.

All functions that take a scale factor assert that this will return true. If you’re sourcing scale factors from anywhere other than winit, it’s recommended to validate them using this function before passing them to winit; otherwise, you risk panics.
