|
|
* Yutani is a canvas-based window compositor and manager.
|
|
* It employs shared memory to provide clients access to
|
|
* canvases in which they may render, while using a packet-based
|
|
* socket interface to communicate actions between the server
|
|
* and client such as keyboard activity, mouse movement, responses
|
|
* to client events, etc., as well as to communicate requests from
|
|
* the client to the server, such as creation of new windows,
|
|
* movement, resizing, and display updates.
