XIM: Allow modifier releases in compose sequences (#26705)
Currently, only non-modifier keys (actually, keysyms) can be part of a compose sequence, and they are matched against the defined compose sequences at the time the key is pressed. The patch allows to use modifier keys an well, but matches them on key release, and only if no other key has been pressed after the modifier. Releasing a non-matched modifier during an ongoing compose sequence only aborts the sequence if any modifier release would have matched. In particular, if no compose sequences with modifiers are specified, the compose mechanism works exactly as without this patch. Even if modifiers are part of a compose sequence, they are not filtered. This is because modifiers affect the keyboard state no matter what we do here and, therefore, filtering them only could confuse clients. The purpose is this extension to the compose mechanism is to allow to make better use of keys in convenient reach for touch typing.
