+/* Xephyr wants ctrl+shift to grab the window, but that conflicts with
+   ctrl+alt+shift key combos. Remember the modifier state on key presses and
+   releases, if mod1 is pressed, we need ctrl, shift and mod1 released
+   before we allow a shift-ctrl grab activation.
+
+   note: a key event contains the mask _before_ the current key takes
+   effect, so mod1_was_down will be reset on the first key press after all
+   three were released, not on the last release. That'd require some more
+   effort.
