get an excess Tab key report when switching back to an OSG
application (usually FlightGear :-). Although KDE has consumed
the Tab, it's sometimes still in the XKeymapEvent's key_vector,
and followed by a Tab KeyRelease event.
Avoid this artifact by
- asking for a "fresh" keymap (via XQueryKeymap()), rather than
using the unreliable(?) XKeymapEvent's key_vector, and by
- flushing all key events on focus-in (to avoid the KeyRelease)
After Super-press, Tab-press, Super-release, Tab-release (note
the wrong release order!) I still get an extra Tab event. But
this is not surprising and not exactly wrong either. Also it's
hard to avoid, as we can't see what happened to the keyboard
before we regained focus.
