interactive-x11: beef up select_events a bit - Specify in detail which parts of the events we care about. In theory the X server should not bother us with things we didn't ask for. In practice it still does, but oh well. - Use the _aux version of select_events. This is the correct one to use, the non-aux version is useless. Signed-off-by: Ran Benita <ran234@gmail.com>
