When adding the frame callback API in 70040166 we decided on a common idiom for adding callbacks which would return an opaque pointer representing the closure for the callback. This pointer can then be used to later remove the callback. The closure can also contain an optional callback to invoke when the user data parameter is destroyed. The resize callback didn't work this way and instead had an integer handle to identify the closure. This patch changes it to work the same way as the frame callback.
