The IBus gtk+ module uses bits 24 and 25 on the GdkEventKey.state mask
to mark events in order to prevent a loop that would otherwise happen
due to how it processes events.

You should process it like any other mask, use bit-wise operations. i.e.

if (state & GDK_CONTROL_MASK) { /* Ctrl bit is set */ }
