warning: unnecessary `unsafe` block

Can these unsafe calls be removed? (I'd be happy to PR):

   = note: `#[warn(unused_unsafe)]` on by default

Oh, such a shame, there are #![allow(warnings)] in both repos. If you want - go ahead with PR returning warnings back! :)

For rand - better mark webgl's rand as unsafe - because it is unsafe on linux and windows.
