To avoid passing a queue type for each kind of input (pointer, key), introduce package input for mapping a handler key to all input events. Future input sources can be added without changes to programs, and as an added bonus, event ordering is preserved across input sources. Signed-off-by: Elias Naur <mail@eliasnaur.com>
