Function gmsh_sys::gmshModelOccAddRectangle

pub unsafe extern "C" fn gmshModelOccAddRectangle(
    x: f64, 
    y: f64, 
    z: f64, 
    dx: f64, 
    dy: f64, 
    tag: c_int, 
    roundedRadius: f64, 
    ierr: *mut c_int
) -> c_int

Add a rectangle with lower left corner at (x, y, z) and upper right corner at (x + dx, y + dy, z). If tag is positive, set the tag explicitly; otherwise a new tag is selected automatically. Round the corners if roundedRadius is nonzero. Return the tag of the rectangle.
