Function mupdf_sys::fz_union_rect

pub unsafe extern "C" fn fz_union_rect(a: fz_rect, b: fz_rect) -> fz_rect

Compute union of two rectangles.

Given two rectangles, update the first to be the smallest axis-aligned rectangle that encompasses both given rectangles. If either rectangle is infinite then the union is also infinite. If either rectangle is empty then the union is simply the non-empty rectangle. Should both rectangles be empty, then the union is also empty.
