Generally, font-dependent/relative units don’t get text-only-zoomed, because the font they’re relative to should be zoomed already.

pub(crate) fn map(&self, op: impl FnMut(f32) -> f32) -> Self

pub fn to_computed_pixel_length_without_context(&self) -> Result<CSSFloat, ()>

Get an absolute length from a px value.

pub fn to_px_if_absolute(&self) -> Option<CSSFloat>

Returns the value as a px-canonical length (absolute lengths only).
