The compositor acts as a relay between applications using the text-input protocol and input methods using the input-method protocol. This change implements the basic but useful support for input-method, leaving out grabs as well as popups.

/**
|
|
* The relay structure manages the relationship between text-input and
|
|
* input_method interfaces on a given seat. Multiple text-input interfaces may
|
|
* be bound to a relay, but at most one will be focused (reveiving events) at
|
|
* a time. At most one input-method interface may be bound to the seat. The
|
|
* relay manages life cycle of both sides. When both sides are present and
|
|
* focused, the relay passes messages between them.
|
|
*
|
|
* Text input focus is a subset of keyboard focus - if the text-input is
|
|
* in the focused state, wl_keyboard sent an enter as well. However, having
|
|
* wl_keyboard focused doesn't mean that text-input will be focused.
