This requests to make this invisible to the user.
Actually the precise semantics of this function depend on the window system currently in use, and if you don't have a multi-windowining system this function may in-fact do nothing.
This function does not implicitly allocate the given this framebuffer before hiding it.
<note>Since Cogl doesn't explicitly track the visibility status of onscreen framebuffers it wont try to avoid redundant window system requests e.g. to show an already visible window. This also means that it's acceptable to alternatively use native APIs to show and hide windows without confusing Cogl.</note>
