In previous releases there were separate
Pane objects created
by the mux and gui layers, respectively. This is no longer the case: there is
now just the underlying mux pane which is referred to in these docs as
for the sake of simplicity.
A Pane object is typically passed to your code via an event callback. A Pane object is a handle to a live instance of a Pane that is known to the wezterm process. A Pane object tracks the psuedo terminal (or real serial terminal) and associated process(es) and the parsed screen and scrollback.
A Pane object can be used to send input to the associated processes and introspect the state of the terminal emulation for that pane.
