compositors listen on the socket id "hilbert.compositor".
|
|
|
|
there is a one-to-one correspondence between sockets to the compositor and
|
|
windows. when a socket is opened, a window is created, and when a socket is
|
|
closed, its window is destroyed. this socket can be gifted to another process,
|
|
and the other process then becomes the window's owner.
|
|
|
|
data types:
|
|
|
|

|
opaque dword (result of encode color system call).
